Teach two-address lowering how to unfold a load to open up commuting
opportunities. For example, this lets it emit this:

   movq (%rax), %rcx
   addq %rdx, %rcx

instead of this:

   movq %rdx, %rcx
   addq (%rax), %rcx

in the case where %rdx has subsequent uses. It's the same number
of instructions, and usually the same encoding size on x86, but
it appears faster, and in general, it may allow better scheduling
for the load.

Fix an unintentional commit. I think I typed "git svn dcommit" in the wrong branch.

I was trying to do some refactoring on the copyRegToReg, but this is realyl a work in progress and not generally useful yet.

Fix lowering of VECTOR_SHUFFLE on SPU. Old algorithm

Add support for returning multiple vectors via sret, which is how the ARM target expects the intrinsics to work.

Restore a call to rememberInstruction which was accidentally dropped
in refactoring.

Add a TODO comment.

Include the use kind along with the expression in the key of the
use sharing map. The reconcileNewOffset logic already forces a
separate use if the kinds differ, so incorporating the kind in the
key means we can track more sharing opportunities.

More sharing means fewer total uses to track, which means smaller
problem sizes, which means the conservative throttles don't kick
in as often.

Use calloc instead of new/memset, it is more efficient when the set is very large.

Fix ScalarEvolution's "exhaustive" trip count evaluation code to avoid
assuming that loops are in canonical form, as ScalarEvolution doesn't
depend on LoopSimplify itself. Also, with indirectbr not all loops can
be simplified. This fixes PR7416.
