Metadata printing with -b, -H, or -n flags suffered from a few flaws:
1) -b/offset printing was broken when used in conjunction with -o
2) With -o, bsdgrep did not print metadata for every match/line, just
the first match of a line
3) There were no tests for this
Address these issues by outputting this data per-match if the -o flag is
specified, and prior to outputting any matches if -o but not --color,
since --color alone will not generate a new line of output for every
iteration over the matches.
To correct -b output, fudge the line offset as we're printing matches.
While here, make sure we're using grep_printline in -A context. Context
printing should *never* look at the parsing context, just the line.
The tests included do not pass with gnugrep in base due to it exhibiting
similar quirky behavior that bsdgrep previously exhibited.

We should not set an arbitrary cap on the number of matches on a line,
and in any case MAX_LINE_MATCHES of 32 is much too low. Instead, if we
match more than MAX_LINE_MATCHES, keep processing and matching from the
last match until all are found.
For the regression test, we produce 4096 matches (larger than we expect
we'll ever set MAX_LINE_MATCHES) and make sure we actually get 4096
lines of output with the -o flag.
We'll also make sure that every distinct line is getting its own line
number to detect line metadata not being printed as appropriate along
the way.

-w flag matching with an empty pattern was generally 'broken', allowing
matches to occur on any line whether or not it actually matches -w
criteria.
This fix required a good amount of refactoring to address. procline()
is altered to *only* process the line and return whether it was a match
or not, necessary to be able to short-circuit the whole function in case
of this matchall flag. -m flag handling is moved out as well because it
suffers from the same fate as context handling if we bypass any actual
pattern matching.
The matching context (matches, mostly) didn't previously exist outside
of procline(), so we go ahead and create context object for file
processing bits to pass around. grep_printline() was created due to
this, for the scenarios where the matches don't actually matter and we
just want to print a line or two, a la flushing the context queue and
no -o or --color specified.
Damage from this broken behavior would have been mitigated by the fact
that it is unlikely users would invoke grep -w with an empty pattern.
This was identified while checking PR 105221 for problems it this may
cause in BSD grep, but PR 105221 is *not* a report of this behavior.

-w and -v flag matching was mostly functional but had some minor
problems:
1. -w flag processing only allowed one iteration through pattern
matching on a line. This was problematic if one pattern could match
more than once, or if there were multiple patterns and the earliest/
longest match was not the most ideal, and
2. Previous work "fixed" things to not further process a line if the
first iteration through patterns produced no matches. This is clearly
wrong if we're dealing with the more restrictive -w matching.
#2 breakage could have also occurred before recent broad rewrites, but
it would be more arbitrary based on input patterns as to whether or not
it actually affected things.
Fix both of these by forcing a retry of the patterns after advancing
just past the start of the first match if we're doing more restrictive
-w matching and we didn't get any hits to start with. Also move -v flag
processing outside of the loop so that we have a greater change to match
in the more restrictive cases. This wasn't strictly wrong, but it could
be a little more error prone.
While here, introduce some regressions tests for this behavior and fix
some excessive wrapping nearby that hindered readability. GNU grep
passes these new tests.

[Assembler] Enable nicer diagnostics for inline assembly.
Fixed test.
Summary:
Enables source location in diagnostic messages from the backend.
This is after parsing, during finalization. This requires the
SourceMgr, the inline assembly string buffer, and DiagInfo to still
be alive after EmitInlineAsm returns.
This patch creates a single SourceMgr for inline assembly inside the
AsmPrinter. MCContext gets a pointer to this SourceMgr. Using one
SourceMgr per call to EmitInlineAsm would make it difficult for
MCContext to figure out in which SourceMgr the SMLoc is located,
while a single SourceMgr can figure it out if it has multiple
buffers.
The Str argument to EmitInlineAsm is copied into a buffer and owned
by the inline asm SourceMgr. This ensures that DiagHandlers won't
print garbage. (Clang emits a "note: instantiated into assembly
here", which refers to this string.)
The AsmParser gets destroyed before finalization, which means that
the DiagHandlers the AsmParser installs into the SourceMgr will be
stale. Restore the saved DiagHandlers.
Since now we're using just one SourceMgr for multiple inline asm
strings, we need to tell the AsmParser which buffer it needs to parse
currently. Hand a buffer id -- returned from SourceMgr::
AddNewSourceBuffer -- to the AsmParser.

However, on x86_64 it means the RAX and RDX registers, and on 16-bit

Add new register classes in `X86RegisterInfo.td` to support these
cases, and amend the logic in `getRegForInlineAsmConstraint` to cope
with different subtargets. Also add a test case, derived from

GNU libtool checks the output from invoking the linker with --version

include those same strings to fool libtool.
Quoting from a comment in the change:
This is somewhat ugly hack, but in reality, we had no choice other
than doing this. Considering the very long release cycle of Libtool,
it is not easy to improve it to recognize LLD as a GNU compatible
linker in a timely manner. Even if we can make it, there are still a
lot of "configure" scripts out there that are generated by old
version of Libtool. We cannot convince every software developer to
