When compiling this for mips32 on gcc-6.x, we'd hit issues where we
don't have 64 bit atomics on mips32.
gcc implements this using libatomic, which we don't currently include
in our freebsd-gcc compiler packages.
So for now add this work around so mips32 works. It's also fine for
mips64. We can fix this later once we get libatomic included.

[clang][Sema] Fix PR47676: Handle dependent AltiVec C-style cast
Fix premature decision in the presence of type-dependent expression
operands on whether AltiVec vector initializations from single
expressions are "splat" operations.
Verify that the instantiation is able to determine the correct cast
semantics for both the scalar type and the vector type case.
Note that, because the change only affects the single-expression case
(and the target type is an AltiVec-style vector type), the
replacement of a parenthesized list with a parenthesized expression
does not change the semantics of the program in a program-observable
manner.

[Sema] Introduce BuiltinAttr, per-declaration builtin-ness
Instead of relying on whether a certain identifier is a builtin,
introduce BuiltinAttr to specify a declaration as having builtin
semantics.
This fixes incompatible redeclarations of builtins, as reverting the
identifier as being builtin due to one incompatible redeclaration
would have broken rest of the builtin calls.
Mostly-compatible redeclarations of builtins also no longer have
builtin semantics. They don't call the builtin nor inherit their
attributes.
A long-standing FIXME regarding builtins inside a namespace enclosed
in extern "C" not being recognized is also addressed.
Due to the more correct handling attributes for builtin functions are
added in more places, resulting in more useful warnings.
Tests are updated to reflect that.
Intrinsics without an inline definition in intrin.h had `inline` and
`static` removed as they had no effect and caused them to no longer
be recognized as builtins otherwise.
A pthread_create() related test is XFAIL-ed, as it relied on it being
recognized as a builtin based on its name.
The builtin declaration syntax is too restrictive and doesn't allow
custom structs, function pointers, etc.
It seems to be the only case and fixing this would require reworking
the current builtin syntax, so this seems acceptable.
Fixes PR45410.

resolution for <https://bugs.llvm.org/show_bug.cgi?id=47181>.
The cache implementation depends on dl_iterate_phdr(3) ensuring that its
callbacks are not called simultaneously for multiple threads, but that
is only the case for the dl_iterate_phdr() implementation in rtld.
In a statically linked executable, libc's dl_iterate_phdr() is used,
which does no such locking. If multiple threads then call into the
unwinder at the same time, it is possible to trigger a segfault.
In particular, the statically linked lld which is built during the
cross-tools stage can segfault in this way, because it starts multiple
worker threads that can exit in parallel. Since our pthread_exit(3)
invokes the unwinder, it will therefore call into it in parallel too.

[PowerPC] enable atomic.c in compiler_rt and do not check and forces
lock/lock_free decisions in compiled time
Summary:
Enables atomic.c in compiler_rt and forces clang to not emit a call for runtime
decision about lock/lock_free. At compiling time, if clang can't decide if
atomic operation can be lock free, it emits calls to external functions like
`__atomic_is_lock_free`, `__c11_atomic_is_lock_free` and
`__atomic_always_lock_free`, postponing decision to a runtime check. According
to LLVM code documentation, the mechanism exists due to differences between
x86_64 processors that can't be decided at runtime.
On PowerPC and PowerPCSPE (32 bits), we already know in advance it can't be lock
free, so we force the decision at compile time and avoid having to implement it
in an external library.
This patch was made after 32 bit users testing the PowePC32 bit ISO reported
llvm could not be compiled with in-base llvm due to `__atomic_load8` not
implemented.

lldb: shorten thread names to make logs easier to follow
lldb prepends the thread name to log entries, and the existing thread

results in "error: anonymous union can only contain non-static data

Add a workaround to prevent endless recursion in compiler-rt.
SPARC and MIPS CPUs don't have special instructions to count

implemented as simple wrappers around the compiler built-in
__builtin_clz(), assuming these will expand to either 32-bit
CPU instructions or calls to __clzsi2 and __ctzsi2.
Unfortunately, our GCC 4.2 probably thinks that because the operand is
stored in a 64-bit register, it might just be a better idea to invoke
its 64-bit equivalent, simply resulting into endless recursion. Fix this
by defining __builtin_clz and __builtin_ctz to __clzsi2 and __ctzsi2
