It is safe to remat a value killed by phis.

The source live range is recomputed using shrinkToUses() which does
handle phis correctly.  The hasPHIKill() condition was relevant in the
old days when ReMaterializeTrivialDef() tried to recompute the live
range itself.

The shrinkToUses() function will mark the original def as dead when no
more uses and phi kills remain.  It is then removed by
runOnMachineFunction().

One more patch towards JIT support for Mips.
- Add TSFlags for the instruction formats. The idea here is to use
  as much encoding as possible from getBinaryCodeForInstr, and having
  TSFLags formats for that would make it easier to encode most part
  of the instructions (since Mips encodings are pretty straightforward)
- Improve the mips mechanism for compilation callback
- Add Mips specific code for invalidating the instruction cache
- Next patch will address wrong tablegen encoding

Commit msg added by my own but the patch is from Sasa Stankovic.

Teach the foldable tables about 128-bit AVX instructions and make the
alignment check for 256-bit classes more strict. There're no testcases
but we catch more folding cases for AVX while running single and multi
sources in the llvm testsuite.

Since some 128-bit AVX instructions have different number of operands
than their SSE counterparts, they are placed in different tables.

256-bit AVX instructions should also be added in the table soon. And
there a few more 128-bit versions to handled, which should come in
the following commits.
