Use an array instead of a DenseMap to cache persistent IDs -> IdentifierInfo*.  This leads to a 4% speedup at -fsyntax-only using PTH.

- Remove PTHManager.cpp.  Move all of its functions to PTHLexer.cpp since some of the internal methods are used by PTHLexer (their implementations are intertwined.)  This enables some important inlining opportunities at -O3.

- Don't construct an std::vector<Token> prior to feeding PTH tokens to the Preprocessor.  Stream them off the PTH file directly.

- Added method "setPTHManager" that will be called by the driver to install
  a PTHManager for the Preprocessor.
- Fixed some comments.
- Added EnterSourceFileWithPTH to mirror EnterSourceFileWithLexer.

Added PTHManager, a utility class that will be used by Preprocessor to lazily create PTHLexer objects for pre-tokenized files.

- Output 32 bit integers using bit-shifting + write of individual bytes.
  This is motivated because we aren't guaranteed to load 32-bit ints of the mmaped PTH file at 4-byte offsets.
- Don't emit flags for IdentifierInfos.  These are lazily populated by the Preprocessor/Parser.
- Only write out tokens for files with absolute paths.  This is potentially temporary, but simplifies things for now.

This may be the case on 64-bit systems. Whether that fact is a bug is a different question, but it's easy to cure the symptom.

would not work because this list is not yet constructed. This is in preparation
for doing semantic check on viability of setter/getter method declarations.
