signal handler reads sa_sigaction when a concurrent sigaction call can modify it
as the result in could try to call SIG_DFL or a partially overwritten function pointer

Summary:
Always quote suppressions files given to *_OPTIONS.
This will make it not break when given full Windows paths (otherwise,
parsing would stop after the drive's letter + ':').

Also fix one or two cases where the suppression files' extensions were
not *.supp.

This reverts commit r224451. It caused us to reject some valid existing
code.

This code appears to run in non-error cases as well as error cases. If
the scope of a DependentScopeDeclRefExpr is still incomplete it probably
means we still have more instantiation to do.

Repared support for warnings -Wkeyword-macro and -Wreserved-id-macro.
The warning -Wkeyword-macro now is not issued in patterns that are used
in configuration scripts:

    #define inline

also for 'const', 'extern' and 'static'. If macro repalcement is identical
to macro name, the warning also is not issued:

    #define volatile volatile

And finally if macro replacement is also a keyword identical to the replaced
one but decorated with leading/trailing underscores:

    #define inline __inline
    #define inline __inline__
    #define inline _inline // in MSVC compatibility mode

Warning -Wreserved-id-macro is off by default, it could help catching
things like:

    #undef __cplusplus

ParseCXXNonStaticMemberInitializer stashes away all the tokens for the
initializer and an additional EOF token to denote where the initializer
ends.  However, it is possible for ParseLexedMemberInitializer to get
its hands on the "real" EOF token; since the two tokens are
indistinguishable, we end up consuming the EOF and descend into madness.

Instead, make it possible to tell which EOF token we are looking at.

This fixes PR21872.

It is often convenient to use -save-temps to collect the intermediate
results of a compilation, e.g., when triaging a bug report. Besides the
temporary files for preprocessed source and assembly code, this adds the
unoptimized bitcode files as well.

This adds a new BackendJobAction, which is mostly mechanical, to run after
the CompileJobAction. When not using -save-temps, the BackendJobAction is
combined into one job with the CompileJobAction, similar to the way the
integrated assembler is handled. I've implemented this entirely as a
driver change, so under the hood, it is just using -disable-llvm-optzns
to get the unoptimized bitcode.

Based in part on a patch by Steven Wu.

The ARM Architecture Reference Manual states the following:
  LDM{,IA,DB}:
    The SP cannot be in the list.
    The PC can be in the list.
    If the PC is in the list:
      • the LR must not be in the list
      • the instruction must be either outside any IT block, or the last
        instruction in an IT block.
  POP:
    The PC can be in the list.
    If the PC is in the list:
      • the LR must not be in the list
      • the instruction must be either outside any IT block, or the last
        instruction in an IT block.
  PUSH:
    The SP and PC can be in the list in ARM instructions, but not in Thumb
    instructions.

Near as I can tell prefixes are ignored on these instructions except for a comment in the Intel docs about 0xf3. Binutils disassembler seems to ignore prefixes on these instructions.
