Summary:
During make check-all on Solaris, I see several instances of this warning:

clang-6.0: warning: argument unused during compilation: '-pthread' [-Wunused-command-line-argument]

Since Solaris 10, libpthread has been folded into libc, so there's nothing to do.  gcc
just ignores -pthread here.  Darwin claims the option to silence the warning, and
this patch follows that lead.

This was caught by buildbots when submitting rL324319.

[ELF] - Re-commit r324322 "Use InitTargetOptionsFromCodeGenFlags/ParseCommandLineOptions for parsing LTO options.".

With fix:
Keep logic that ignores -plugin-opt=mcpu=x86-64 -plugin-opt=thinlto,
add checks for those to testcases.

Original commit message:

[ELF] - Use InitTargetOptionsFromCodeGenFlags/ParseCommandLineOptions for parsing LTO options.

gold plugin uses InitTargetOptionsFromCodeGenFlags + 
ParseCommandLineOptions for parsing LTO options.
Patch do the same change for LLD.

Such change helps to avoid parsing/whitelisting LTO
plugin options again on linker side, what can help LLD
to automatically support new -plugin-opt=xxx options
passed.

Summary:
This patch adds spaces around angle brackets in text proto Google style.
Previously these were detected as template openers and closers, which happened
to have the expected effect. Now we detect them as scope openers and closers
similarly to the way braces are handled in this context.

It is better to update pointer of the DISuprogram before we call RAUW for
still live arguments of the function, because with the change reviewed in
D42541 in RAUW we compare DISubprograms rather than functions itself.

This adds the CSDB instruction, which is a new barrier instruction
described by the whitepaper at [1].

This is in encoding space which was previously executed as a NOP, so it is
available for all targets that have the relevant NOP encoding space. This
matches the binutils behaviour for these instructions [2][3].

This adds most of the FP16 codegen support, but these areas need further work:

- FP16 literals and immediates are not properly supported yet (e.g. literal
  pool needs work),
- Instructions that are generated from intrinsics (e.g. vabs) haven't been
  added.

This will be addressed in follow-up patches.

Summary:
This method is trying to use the truncate node to find which SETCC operand should be replaced directly with the extended load.

This used to work correctly because all uses of the original load were replaced by the truncate before this function was called. So this was used to effectively bypass the truncate and find the load under it.

All but one of the callers now call this before the truncate has replaced the laod so the setcc doesn't yet use the truncate. To account for this we should pass the original load instead.

I changed the order of that one caller to make this work there too.

I don't have a test case because this is probably hidden by later DAG combines causing the extend and truncate to cancel out. I assume this way is a little more efficient and matches what was originally intended.

Summary:
This patch adds some initial support for Windows control flow guard. At
the end of the day, the linker needs to synthesize a table of RVAs very
similar to the structured exception handler table (/safeseh).

Both /safeseh and /guard:cf take sections of symbol table indices
(.sxdata and .gfids$y) and turn them into RVA tables referenced by the
load config struct in the CRT through special symbols.
