Declare PerIDCache as IdentifierInfo** instead of void*. This is just cleaner. No performance change.

PTH:
...
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.

In PTHLexer::DiscardToEndOfLine() use Lex() instead of AdvanceToken(). This handles transitions in the preprocessor state.

PTHLexer:

- Move out logic for handling the end-of-file to LexEndOfFile (to match the Lexer) class. The logic now mirrors the Lexer class more, which allows us to pass most of the Preprocessor test cases.

PTHLexer:

PTHLexer:
...
- Rename 'CurToken' and 'LastToken' to 'CurTokenIdx' and 'LastTokenIdx'
respectively.
- Add helper methods GetToken(), AdvanceToken(), AtLastToken() to abstract away
details of the token stream. This also allows us to easily replace their
implementation later.

- Move static function IsNonPragmaNonMacroLexer into Preprocessor.h.
...
- Add variants of IsNonPragmaNonMacroLexer to accept an IncludeMacroStack entry
(simplifies some uses).
- Use IsNonPragmaNonMacroLexer in Preprocessor::LookupFile.
- Add 'FileID' to PreprocessorLexer, and have Preprocessor query this fileid
when looking up the FileEntry for a file
Performance testing of -Eonly on Cocoa.h shows no performance regression because
of this patch.
