De-unionize fields in Token class.
...
- 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%.

Add ugly "test harness" for PTHLexer that is not enabled by default. The
...
(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.

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

also, but today is not that day.

Experimental post-pass scheduling support. Post-pass scheduling
...
is currently off by default, and can be enabled with
-disable-post-RA-scheduler=false.
This doesn't have a significant impact on most code yet because it doesn't
yet do anything to address anti-dependencies and it doesn't attempt to
disambiguate memory references. Also, several popular targets
don't have pipeline descriptions yet.
The majority of the changes here are splitting the SelectionDAG-specific
code out of ScheduleDAG, so that ScheduleDAG can be moved to
libLLVMCodeGen.a. The interface between ScheduleDAG-using code and
the rest of the scheduling code is somewhat rough and will evolve.
