Cherry-pick lld r315658 by Rui Ueyama:
This is not a mechanical transformation. Even though I believe this
patch is correct, I'm not 100% sure if lld with this patch behaves
exactly the same way as before on all edge cases. At least all tests
still pass.
I'm submitting this patch because it took almost a day to understand
this function, and I don't want to lose it.
This fixes jemalloc assertion failures observed at startup with i386
binaries and an lld-linked libc.so.

Don't trigger -Wuser-defined-literals for system headers
Summary:
In D41064, I proposed adding `#pragma clang diagnostic ignored
"-Wuser-defined-literals"` to some of libc++'s headers, since these
warnings are now triggered by clang's new `-std=gnu++14` default:
$ cat test.cpp
#include <string>

Both @aaron.ballman and @mclow.lists felt that adding this workaround
to the libc++ headers was the wrong way, and it should be fixed in
clang instead.
Here is a proposal to do just that. I verified that this suppresses
the warning, even when -Wsystem-headers is used, and that the warning
is still emitted for a declaration outside of system headers.

Don't create a dummy __tls_get_addr.
We just don't need one with the current setup.
We only error on undefined references that are used by some
relocation.
If we managed to relax all uses of __tls_get_addr, no relocation uses
it and we don't produce an error.
This is less code and fixes the case were we fail to relax. Before we
would produce a broken output, but now we produce an error.
Pull in r320390 from upstream lld trunk (by Rafael Espindola):
Create reserved symbols early so they can be versioned.
This fixes pr35570.
We were creating these symbols after parsing version scripts, so they
could not be versioned.
We cannot move the version script parsing later because we need it for
lto.
One option is to move both addReservedSymbols and
createSyntheticSections earlier. The disadvantage is that some
sections created by createSyntheticSections replace other input
sections. For example, gdb index replaces .debug_gnu_pubnames, so it
wants to run after gc sections so that it can set S->Live to false.
What this patch does instead is to move just the ElfHeader creation
early.
Pull in r320412 from upstream lld trunk (by Rafael Espindola):
Handle symbols pointing to output sections.
Now that gc sections runs after linker defined symbols are added it

Previously, lld exited with an error status if the only option given to

makes lld behave like GNU.
Note that even with this patch, lld's -v and --version options behave
slightly differently than GNU linkers' counterparts. For example,
if you run ld.bfd -v -v, the version string is printed out twice.
But that is an edge case that I don't think we need to take care of.

/usr/src/contrib/compiler-rt/lib/asan/asan_poisoning.cc:36
"((AddrIsAlignedByGranularity(addr))) != (0)" (0x0, 0x0)
This is because AddressSanitizer expects all the TLS data in the program
to be aligned to at least 8 bytes.
Before the jemalloc 5.0.0 update, all the TLS data in the i386 version
of libc.so added up to 80 bytes (a multiple of 8), but 5.0.0 made this
grow to 2404 bytes (not a multiple of 8). This is due to added caching
data in jemalloc's internal struct tsd_s.
To fix AddressSanitizer, ensure this struct is aligned to at least 16
bytes, which can be done unconditionally for all architectures. (An
earlier version of the fix aligned the struct to 8 bytes, but only for
ILP32 architectures. This was deemed unnecessarily complicated.)

If unwinding stops due to hitting the end of the call chain, the return
value is supposed to be _URC_END_OF_STACK; other values indicate internal
errors. The return value from get_eit_entry() is now returned without
translating it to _URC_FAILURE, so that callers can see _URC_END_OF_STACK
when it happens.
When raising an exception, the unwinder searches for a catch handler and if
none is found it should invoke std::terminate() with the uncaught exception
as the "current" exception. Before this change, the terminate handler was
invoked with no exception as current (abi::__cxa_current_exception_type()
returned NULL), because the return value from the unwinder indicated an
internal failure in unwinding. It turns out that was because all errors
from get_eit_entry() were translated to _URC_FAILURE. Now the error is
returned untranslated, which allows _URC_END_OF_STACK to percolate upwards
to throw_exception() in libcxxrt. When it sees that return status it
properly calls std::terminate() with the uncaught exception installed
as the current exception, allowing custom terminate handlers to work
with it.

where the source register is also the first destination register.
If this is the case, and we raise an exception in the middle of the
instruction, for example the load is across two pages and the second page
isn't mapped, QEMU will have overwritten the address with invalid data.
This is a valid behaviour in most cases, with the exception of when a
destination register is also use in address generation. As such switch
the order of the registers to ensure the address register is second so it
will be written to second, after any exceptions have happened.
This has been acknowledged in upstream QEMU, however as the workaround is
simple also handle it here.

How network VF works with hn(4) on Hyper-V in non-transparent mode:
- Each network VF has a cooresponding hn(4).
- The network VF and the it's cooresponding hn(4) have the same hardware
address.
- Once the network VF is up, e.g. ifconfig VF up:
o All of the transmission should go through the network VF.
o Most of the reception goes through the network VF.
o Small amount of reception may go through the cooresponding hn(4).
This reception will happen, even if the the cooresponding hn(4) is
down. The cooresponding hn(4) will change the reception interface
to the network VF, so that network layer and application layer will
be tricked into thinking that these packets were received by the
network VF.
o The cooresponding hn(4) pretends the physical link is down.
- Once the network VF is down or detached:
o All of the transmission should go through the cooresponding hn(4).
o All of the reception goes through the cooresponding hn(4).
o The cooresponding hn(4) fallbacks to the original physical link
detection logic.

the network VF will be detached, while the network communication to the
VM must not be cut off. In order to reach this level of live migration
transparency, we use failover mode lagg(4) with the network VF and the
cooresponding hn(4) attached to it.
To ease user configuration for both network VF and non-network VF, the
lagg(4) will be created by the following rules, and the configuration
of the cooresponding hn(4) will be applied to the lagg(4) automatically.

PR33902: Invalidate line number cache when adding more text to
existing buffer.
This led to crashes as the line number cache would report a bogus
line number for a line of code, and we'd try to find a nonexistent
column within the line when printing diagnostics.
This fixes an assertion when building the graphics/champlain port.

[CodeGenPrepare] Cut off FindAllMemoryUses if there are too many uses.
This avoids excessive compile time. The case I'm looking at is
Function.cpp from an old version of LLVM that still had the giant
memcmp string matcher in it. Before r308322 this compiled in about 2
minutes, after it, clang takes infinite* time to compile it. With
this patch we're at 5 min, which is still bad but this is a
pathological case.
The cut off at 20 uses was chosen by looking at other cut-offs in LLVM
for user scanning. It's probably too high, but does the job and is
very unlikely to regress anything.
Fixes PR33900.
* I'm impatient and aborted after 15 minutes, on the bug report it was
killed after 2h.
Pull in r308986 from upstream llvm trunk (by Simon Pilgrim):
[X86][CGP] Reduce memcmp() expansion to 2 load pairs (PR33914)
D35067/rL308322 attempted to support up to 4 load pairs for memcmp
inlining which resulted in regressions for some optimized libc memcmp
implementations (PR33914).
Until we can match these more optimal cases, this patch reduces the
memcmp expansion to a maximum of 2 load pairs (which matches what we
do for -Os).
This patch should be considered for the 5.0.0 release branch as well

Given an empty pattern (i.e. grep "" A B), bsdgrep(1) would previously exit()
with the appropriate exit code upon encountering an empty file. Likely intended
as an optimization, but this behavior is technically incorrect since an empty
pattern should match every line.

PR32034: Evaluate _Atomic(T) in-place when T is a class or array type.
This is necessary in order for the evaluation of an _Atomic

initializer for class or array type needs.
This fixes an assertion when building recent versions of LinuxCNC.

Create libdl.so.1 as a filter for libc.so.7 which exports public dl*
functions. The functions are resolved from the rtld instead, the goal
of creating library is to avoid errors from the static linker due to
missed libdl. For static binaries, an empty .o is compiled into
libdl.a so that static binaries still get dl stubs from libc.a.
Right now lld cannot create filter objects, disable libdl on arm64
when binutils are not used.

Script commands are processed before unused synthetic sections are
removed. Therefore, if a linker script matches one of these sections
it'll get emitted as an empty output section because the logic for
removing unused synthetic sections ignores script commands which
could have already matched and captured one of these sections. This
patch fixes that by also removing the unused synthetic sections from
the script commands.
