This allows us to turn on reconstruction in the pre alloc splitter, which
fixes a number of miscompilations.

Enhance logic in X86DAGToDAGISel::PreprocessForRMW which move load inside callseq_start to allow it to be folded into a call. It was not considering the cases where a token factor is between the load and the callseq_start.

reference! This old semantics probably did not meet the expectations.
With this patch, chained assignments happen to the right object.

the content cache pointer.  This saves 105876 bytes on
cocoa.h because it shrinks the SLocEntry union, which
we have a big array of.  It would be nice to use 
PointerIntPair here, but we can't because it is in a 
union.

tidy up SDUse and related code.
 - Replace the operator= member functions with a set method, like
   LLVM Use has, and variants setInitial and setNode, which take
   care up updating use lists, like LLVM Use's does. This simplifies
   code that calls these functions.
 - getSDValue() is renamed to get(), as in LLVM Use, though most
   places can either use the implicit conversion to SDValue or the
   convenience functions instead.
 - Fix some more node vs. value terminology issues.

Also, eliminate the one remaining use of SDOperandPtr, and
SDOperandPtr itself.

This reduces fsyntax-only time on c99-intconst-1.c from 2.43s down to 
2.01s (20%), reducing the number of fileid lookups from 2529040 linear 
and 64771121 binary to 5625902 linear and 4151182 binary.

This knocks getFileID down to only 4.6% of compile time on this testcase.
At this point, malloc/free is over 35% of compile time, primarily allocating
MacroArgs objects and their argument preexpansion vectors.

I don't feel like malloc avoiding right now, so I'm just going to call
this good.

of a macro.  Since these tokens may themselves be from macro 
expansions, we need to resolve down to the spelling loc when the
macro ends up being instantiated.  Instead of resolving this for
each token expanded from the macro definition, just do it once when
the macro is defined.  This speeds up clang on c99-intconst-1.c from
2.66s to 2.43s (9.5%), reducing the FileID lookups from 407244 linear and
114175649 binary to 2529040 linear and 64771121 binary.

the GCC testsuite from 3.64s to 2.66s (36%).  This reduces the number of
binary search FileID lookups from 251570522 to 114175649 on this testcase.

- Rename fcmp.ll test to fcmp32.ll, start adding new double tests to fcmp64.ll
- Fix select_bits.ll test
- Capitulate to the DAGCombiner and move i64 constant loads to instruction
  selection (SPUISelDAGtoDAG.cpp).

  <rant>DAGCombiner will insert all kinds of 64-bit optimizations after
  operation legalization occurs and now we have to do most of the work that
  instruction selection should be doing twice (once to determine if v2i64
  build_vector can be handled by SelectCode(), which then runs all of the
  predicates a second time to select the necessary instructions.) But,
  CellSPU is a good citizen.</rant>
