With this change, most 'g' options are rejected by CompilerInvocation.
They remain only as Driver options. The new way to request debug info
from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}"
and "-dwarf-version={2|3|4}". In the absence of a command-line option
to specify Dwarf version, the Toolchain decides it, rather than placing
Toolchain-specific logic in CompilerInvocation.
Also fix a bug in the Windows compatibility argument parsing
in which the "rightmost argument wins" principle failed.

Summary:
This is the first patch in the series to migrate Triple's (which are ambiguous)
to TargetTuple's (which aren't).
For the moment, TargetTuple simply passes all requests to the Triple object it
holds. Once it has replaced Triple, it will start to implement the interface in
a more suitable way.
This change makes some changes to the public C++ API. In particular,
InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer()
now take TargetTuples instead of Triples. The other public C++ API's have
been left as-is for the moment to reduce patch size.
This commit also contains a trivial patch to clang to account for the C++ API
change. Thanks go to Pavel Labath for fixing LLDB for me.

In clang cc1as_main, when the output file type is “asm”, AsmStreamer
owns a formatted_raw_ostream which has a reference to FDOS
(raw_ostream), so AsmStreamer must be closed before FDOS is closed.

Summary:
This affects other tools so the previous C++ API has been retained as a
deprecated function for the moment. Clang has been updated with a trivial
patch (not covered by the pre-commit review) to avoid breaking -Werror builds.
Other in-tree tools will be fixed with similar patches.
This continues the patch series to eliminate StringRef forms of GNU triples
from the internals of LLVM that began in r239036.
The first time this was committed it accidentally fixed an inconsistency in
triples in llvm-mc and this caused a failure. This inconsistency was fixed in
r239808.

The clang -cc1as options are nearly a strict subset of -cc1. Instead of
duplicating the definitions and documentation, let's go ahead and share the
definitions in a similar way the current handling of combined driver and
frontend flags, eliminating some of the vestigial legacy surrounding the
assembler subcommand.

Code review feedback from Eric Christopher on r204261.
I didn't want to go into too much detail (the revision history should
provide the full stuff) - but I can add more if that's preferred.
Also moved this up to right by the construction of the MCAsmInfo so
there's less chance that other things might sneak in in between.

For those playing at home this produced some fairly subtle behavior. The
sections created in InitMCObjectFileInfo were created without compressed
debug info (a mistake, but not necessarily /broken). Since these
sections were almost always referenced by the existing MCSection object,
this almost worked.
This got weird when we got to handling the relocations for a section.
See ELFObjectWriter::WriteSection where we compute the true section for
a relocation section by simply stripping the ".rela" prefix and then
looking up that section - doing so hit the compression codepath, looked
up .zdebug_blah and found a newly constructed empty section... thus,
things got weird.
This is untestable without a cross-project test (let me know if people
would prefer that to no testing).

The previous change caused the driver to translate -Wa,-L to the
-msave-temp-labels option for cc1as, but cc1as did not accept that option.
This patch follows the same approach used for similar options (-relax-all,
-noexecstack) in the previous patch.
