Preprocessor: improve ACLE 6.4.1, 6.4.2 support

This improves conformance with ACLE 6.4.1.  Define additional macros that
indicate support for the ARM and Thumb instruction set architecture.  This
includes the following set of macros:

  __ARM_ARCH
  __ARM_ARCH_ISA_ARM
  __ARM_ARCH_ISA_THUMB
  __ARM_32BIT_STATE

These help identify the environment that the code is intended to execute on.

Adjust the handling for ACLE 6.4.2 to be more correct.  We would define the
profile as a free-standing token rather than a quoted single character.

Hide the concept of diagnostic levels from lex, parse and sema

The compilation pipeline doesn't actually need to know about the high-level
concept of diagnostic mappings, and hiding the final computed level presents
several simplifications and other potential benefits.

The only exceptions are opportunistic checks to see whether expensive code
paths can be avoided for diagnostics that are guaranteed to be ignored at a
certain SourceLocation.

This commit formalizes that invariant by introducing and using
DiagnosticsEngine::isIgnored() in place of individual level checks throughout
lex, parse and sema.

Use the ShowInSystemHeader bit consistently for all diagnostics

By describing system header suppressions directly in tablegen we eliminate
special cases in getDiagnosticSeverity().

Dropping the reliance on builtin diagnostic classes when mapping also gets us
closer to the goal of reusing the diagnostic machinery for custom diagnostics.

No change in functionality.

MS ABI: Implement x86_64 RTTI

Summary:
The RTTI scheme for x86_64 is largely the same as the one for i386.

Differences are largely limited to avoiding load-time relocations by
replacing pointers to RTTI metadata with the difference of that data
relative to the load address of the module.

Interestingly, this precludes the possibility of successfully using RTTI
data from another DLL.  The ImageBase reference is always relative to
the current DLL.

Check that the directory does not exist.
Otherwise, it could allows local users to obtain sensitive information or
overwrite arbitrary files via a symlink attack on temporary directories with
predictable names.
