- When lexing in raw mode, null out identifiers.

(a) Remove moved file (SPUAsmPrinter.cpp) to make svn happy.
(b) Remove truncated stores that will never be used.
(c) Add initial support for __muldi3 as a libcall.

- 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.

Output 'ANALYZE' messages to standard error.  This should address the intermixing of 'ANALYZE' and the other diagnostics the clang driver emits to standard error.

 - This is fairly gross but although the code is conceptually the
   same, introducting the union causes gcc 4.2 on x86 (darwin, if that
   matters) to pessimize LexTokenInternal which is critical to our
   preprocessor performance.

This speeds up -Eonly lexing of Cocoa.h by ~4.7% in my timings and
reduces the code size of LexTokenInternal by 8.6%.

Rewrote PTHLexer::Lex by digging through the sources of Lexer again.  Now we can do basic macro expansion using the PTHLexer.

llvm-svn: 59724

(temporary hack) to test the PTHLexer is that whenever we would create a Lexer
object we instead raw lex a memory buffer first and then use the PTHLexer. This
logic exists only to driver the PTHLexer and will be removed/changed in the
future. Note that the regular path using normal Lexer objects is what is used by
default.

llvm-svn: 59723

Added virtual method 'IndirectLex' to PTHLexer.  This will likely get removed in the future when we correctly handle #include processing.

Preprocessor::isCurrentLexer() now takes a PreprocessorLexer* argument to match against CurPPLexer instead of CurLexer.

of doing the lookup_decl, the hash lookup is cheap.  Also,
typeid doesn't happen enough in real world code to worry about
it.

I'd like to eventually get rid of KnownFunctionIDs from Sema
also, but today is not that day.

looking up the "std" identifier is trivial.  Just do it, particularly
since this is only done if the namespace hasn't already been looked up.

and use this to avoid having to call strlen on it.
