Nico Weber fd3e1ad0ce clang-cl: Remove -isystem, add -imsvc.
r260990 exposed -isystem in clang-cl. -isystem adds a directory to the front of
the system include search path. The idea was to use this to point to a hermetic
msvc install, but as it turns out this doesn't work: -isystem then adds the
hermetic headers in front of clang's builtin headers, and clang's headers that
are supposed to wrap msvc headers (say, stdarg.h) aren't picked up at all
anymore.

So revert that, and instead expose -imsvc which works as if the passed
directory was part of %INCLUDE%: The header is treated as a system header, but
it is searched after clang's lib/Header headers.

Fixes half of PRPR26751.

Nico Weber 32b70e0dcf clang-cl: Move /FC from "Unsupported" to "Ignored" list.

David Majnemer cd5855e354 [clang-cl] /EHc should not effect functions with explicit exception specifications

Nico Weber 8714c125e8 clang-cl: Expose -isystem.
Like cl.exe, clang-cl allows adding system include directories via the
INCLUDE env var.  Having a driver flag for this functionality is useful,
so add this too.

(In the future, we probably also want to have a flag alternative to
VCINSTALLDIR as used in MSVCToolChain::getVisualStudioBinaries(), and
a way to override the registry accesses in MSVCToolChain::getWindowsSDKDir()
-- maybe -ivcroot= and -iwinsdkroot=?).

Reid Kleckner 9ce06a4ab8 [clang-cl] /Z7 now generates normal debug info, not just line info
Previously LLVM could not process any debug info we produced, so it
didn't make sense to spend time generating it. Now that it has primitive
support for local variable info, it does make sense to generate normal
debug info.

David Majnemer 2b9349db38 [clang-cl] Add support for /Brepro
The /Brepro flag controls whether or not the compiler should embed
timestamps into the object file.  Object files which do not embed
timestamps are not suitable for incremental linking but are suitable for
hermetic build systems and staged self-hosts of clang.

A normal clang spelling of this flag has been added,
-mincremental-linker-compatible.

Douglas Katzman 3459ce2e5e Stop messing with the 'g' group of options in CompilerInvocation.
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.

Nico Weber 4cc796a614 clang-cl: Don't warn on /bigobj flag
LLVM r217812 made it so that clang-cl implicitly creates bigobj files when
needed, independent of this flag. It looks like cl has this flag to produce obj
flags compatible with MSVS 2003's linker by default, something we don't care
about. Since clang-cl always has /bigobj behavior, don't warn that the flag is
unused, just ignore it silently.

Summary:
By default, 'clang' emits dwarf and 'clang-cl' emits codeview.  You can
force emission of one or both by passing -gcodeview and -gdwarf to
either driver.

David Majnemer 015ce0f68f [clang-cl] Handle -O correctly
We had multiple bugs here:
- We didn't support multiple optimization options in one argument.
  e.g. -O2y-
- We didn't correctly expand -O[12dx] to their respective options.
- We treated -O1 as clang -O1 instead of clang -Os.
- We treated -Ox as clang -O3 instead of clang -O2.  In fact, cl's -Ox
  option is *less* powerful than cl's -O2 option despite -Ox described
  as "Full Optimization".

This fixes PR24003.
