Scott Michel 9e3e4a9219 CellSPU:
- 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>

Dan Gohman f1d38be265 Eliminate the loop that searches through each of the operands
of each use in the SelectionDAG ReplaceAllUses* functions. Thanks
to Chris for spotting this opportunity.

into AddNonLeafNodeToCSEMaps, which is now renamed
AddModifiedNodeToCSEMaps to more accurately reflect its purpose.

Evan Cheng abda665f5f Teach 2addr pass to be do more commuting. If both uses of a two-address instruction are killed, but the first operand has a use before and after the def, commute if the second operand does not suffer from the same issue.

Devang Patel ccfacfff9a Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, DW_AT_APPLE_flags.
DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way.

DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by  a project, irrespective of whether the project used makefile, Xcode or something else.

llvm-gcc patch is next.

Gabor Greif eb61fcf2a1 Simplify the logic of getting hold of a PHI predecessor block.
There is now a direct way from value-use-iterator to incoming block in PHINode's API.
This way we avoid the iterator->index->iterator trip, and especially the costly
getOperandNo() invocation. Additionally there is now an assertion that the iterator
really refers to one of the PHI's Uses.

Dan Gohman 1275e28ded Fold x-0 to x in unsafe-fp-math mode. This comes up in the
testcase from PR3376, and in fact is sufficient to completely
avoid the problem in that testcase.

There's an underlying problem though; TLI.isOperationLegal
considers Custom to be Legal, which might be ok in some
cases, but that's what DAGCombiner is using in many places
to test if something is legal when LegalOperations is true.
When DAGCombiner is running after legalize, this isn't
sufficient. I'll address this in a separate commit.
