Chris Lattner 60f36223a9 move library-specific diagnostic headers into library private dirs. Reduce 
redundant #includes.  Patch by Anders Johnsen!

Chris Lattner 7368d581c1 Split the single monolithic DiagnosticKinds.def file into one 
.def file for each library.  This means that adding a diagnostic
to sema doesn't require all the other libraries to be rebuilt.

Chris Lattner d32480d3db this massive patch introduces a simple new abstraction: it makes 
"FileID" a concept that is now enforced by the compiler's type checker
instead of yet-another-random-unsigned floating around.

This is an important distinction from the "FileID" currently tracked by
SourceLocation.  *That* FileID may refer to the start of a file or to a
chunk within it.  The new FileID *only* refers to the file (and its 
#include stack and eventually #line data), it cannot refer to a chunk.

FileID is a completely opaque datatype to all clients, only SourceManager
is allowed to poke and prod it.

Chris Lattner 53e384f633 Change some terminology in SourceLocation: instead of referring to 
the "physical" location of tokens, refer to the "spelling" location.
This is more concrete and useful, tokens aren't really physical objects!

Chris Lattner 57dab26be1 remove a sneaky version of Diag hiding in PreprocessorLexer.

Chris Lattner 6d27a16b95 Change the Lexer::Diag method to not magically silence warnings, 
force the caller to check instead.  This eliminates the need (and the
risk!) of weird null DiagnosticBuilder's floating around.

Ted Kremenek b0262c1e64 - Default initialize ParsingPreprocessorDirective, ParsingFilename, and 
LexingRawMode in the ctor of PreprocessorLexer.

- PTHLexer: Use "LastToken" instead of "NumToken"

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.

Chris Lattner e05c4dfc42 Remove the last of the old-style Preprocessor::Diag methods.

Ted Kremenek 66312a3ff4 Move some diagnostic handling to PreprocessorLexer.

Ted Kremenek 3060634fba Add virtual dtor to PreprocessorLexer.

Ted Kremenek 6c90efb923 Move LexIncludeFilename from Lexer to PreprocessorLexer. 
PreprocessorLexer now has a virtual method "IndirectLex" which allows it to call the lex method of its subclasses.  This is not for performance intensive operations.
