Ted Kremenek b33ce32bda Preprocessor::getCurrentFileLexer() now returns a PreprocessorLexer* instead of
a Lexer*. This means it will either return the current (normal) file Lexer or a
PTHLexer.

Ted Kremenek a2c3c8d71c Move more cases of using 'CurLexer' to 'CurPPLexer'.
Use PTHLexer::isNextPPTokenLParen() when using the PTHLexer.

Ted Kremenek 45245217bc - 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.

Ted Kremenek 3d9740da29 - Add Lexer::isPragma() accessor for clients of Lexer that aren't friends.
- Add static method to test if the current lexer is a non-macro/non-pragma
  lexer.
- Refactor some code in PPLexerChange to use this static method.
- No performance change.

Ted Kremenek 68ef9fc6ae - Add 'CurPPLexer' to Preprocessor to keep track of the current
PreprocessorLexer, which will either be a 'Lexer' or 'PTHLexer'.
- Added stub field 'CurPTHLexer' to keep track of the current PTHLexer.
- Modified IncludeStackInfo to track both the current PTHLexer and
  current PreprocessorLexer.

Ted Kremenek a0d2a1661a Using llvm::OwningPtr<> for CurLexer and CurTokenLexer. This makes both the ownership semantics of these objects explicit within the Preprocessor and also tightens up the code (explicit deletes not needed).

Ted Kremenek 7c1e61d78b Use PushIncludeMacroStack/PopMacroStack instead of manually pushing/popping from IncludeMacroStack. This is both cleaner and makes the include stack transparently extensible.

Chris Lattner b11c3233d8 Change FormTokenWithChars to take the token kind to form, since all clients
were setting a kind and then forming it.  This is just a minor API cleanup, 
no functionality change.

Chris Lattner c88a23e8d7 Fix the rest of rdar://6243860 hopefully. This requires changing FileIDInfo
to whether the fileid is a 'extern c system header' in addition to whether it
is a system header, most of this is spreading plumbing around.  Once we have that,
PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to
base the system header state on FileIDInfo instead of HeaderSearch.  Finally,
in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness
of a file being entered can be set due to the #includer or the #includee.

Daniel Dunbar 56fdb6ae69 More #include cleaning
- Kill unnecessary #includes in .cpp files. This is an automatic
   sweep so some things removed are actually used, but happen to be
   included by a previous header. I tried to get rid of the obvious
   examples and this was the easiest way to trim the #includes in one
   fell swoop.
 - We now return to regularly scheduled development.

Argyrios Kyrtzidis b3dd1e0889 Allow the preprocessor to cache the lexed tokens, so that we can do efficient lookahead and backtracking.
1) New public methods added:
  -EnableBacktrackAtThisPos
  -DisableBacktrack
  -Backtrack
  -isBacktrackEnabled

2) LookAhead() implementation is replaced with a more efficient one.
3) LookNext() is removed.

Chris Lattner 7a51313d8a Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
