the RR scheduler actually does look at latency values, but it
doesn't use a hazard recognizer so it has no way to know when
a no-op is needed, as opposed to just stalling and incrementing
the cycle count.

that an overflow/carry occured. These are converted into ISD::[SU]ADDO nodes,
which are lowered in a target-independent way into something sane. Eventually,
each target can implement their own method of checking the overflow/carry flags.

(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.

 - 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.
