- Use canonical FileID when using getSpelling() caching.  This
  addresses some cache misses we were seeing with -fsyntax-only on
  Cocoa.h
- Added Preprocessor::getPhysicalCharacterAt() utility method for
  clients to grab the first character at a specified sourcelocation.
  This uses the PTH spelling cache.
- Modified Sema::ActOnNumericConstant() to use
  Preprocessor::getPhysicalCharacterAt() instead of
  SourceManager::getCharacterData() (to get PTH hits).

These changes cause -fsyntax-only to not page in any sources from
Cocoa.h.  We see a speedup of 27%.

Keep "has debug info" big in MachineModuleInfo to avoid circular dependency between AsmPrinter and CodeGen.

PTH: Fix remaining cases where the spelling cache in the PTH file was being missed when it shouldn't.  This shaves another 7% off PTH time for -Eonly on Cocoa.h

this.

It appears the Mips target defaults to list-td, and it has a
regression test that uses a physreg dependence. Such code was
liable to be miscompiled, and now evokes an assertion failure.

Turn off some Destroy calls that are currenly causing double-destruction of ScopedDecls. We will re-enable this later, when we have time to fully solve the ownership issue.

 - Pulled -Xarch processing into this.

 - Get rid of manual creation of forwarding arg array.

 - Use Darwin/CC1 instead of generic GCC cc1 on X86.

DeclContext::KindTrait was not meant to be used outside of DeclContext::CastTo (causes compilation error on MSVC).
Add DeclContext::getDeclKind() and use that instead of DeclContext::KindTrait.

 - --gstabs only goes to Darwin/Assembler when dealing with an
     assembly file from the command line.

 - Relative placement of -o option for cc1 moves depending on
   -fsyntax-only/-S, how quaint.

 - Simple mechanism for group together sets of options so the driver
   can efficiently deal with them as a group (i.e., for forwarding -i*
   to cc1).

 - Use to finish off the major missing pieces of Darwin/CC1 support.
