redundant #includes.  Patch by Anders Johnsen!

.def file for each library.  This means that adding a diagnostic
to sema doesn't require all the other libraries to be rebuilt.

"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.

the "physical" location of tokens, refer to the "spelling" location.
This is more concrete and useful, tokens aren't really physical objects!

force the caller to check instead.  This eliminates the need (and the
risk!) of weird null DiagnosticBuilder's floating around.

  LexingRawMode in the ctor of PreprocessorLexer.

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

llvm-svn: 59690

- 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.

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.
