- Fix nonsensical logic in AssumeSymGE. When comparing 'sym >= constant' and the
  constant is the maximum integer value, add the constraint that 'sym ==
  constant' when the path is deemed feasible.  All other cases are feasible.
- Improve AssumeSymGT. When comparing 'sym > constant' and constant is the
  maximum integer value we know the path is infeasible.
- Add test case for this enhancement to AssumeSymGT.

- Fix nonsensical logic in AssumeSymLE. When comparing 'sym <= constant' and the
  constant is the minimum integer value, add the constraint that 'sym ==
  constant' when the path is deemed feasible.  All other cases are feasible.
- Improve AssumeSymLT to address <rdar://problem/6407949>.  When comparing
  'sym < constant' and constant is the minimum integer value we know the
  path is infeasible.
- Add test case for <rdar://problem/6407949>.

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.

llvm-svn: 60437

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

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.
