3e6bacf7be Next bits of PPC byval handling. Basically functional 
but there are bugs.

08ec4919ea Add support for ppc64 shifts with 7-bit (oversized) shift amount (e.g. PPCshl).

2f13ccc181 Replace SDT_PPCShiftOp in favor of SDTIntBinOps. This allows it to work 
with 32 or 64-bit operands/results.

5f74d1a8dc Fixed a register scavenger bug. If a def is re-defining part of a super register, there must be an implicit def of the super-register on the MI.

we're using SSE or not.  This fixes PR2122.

b33eee09d2 When setting the "unused" info, take into account something like this: 
%r3<def> = OR %x3<kill>, %x3

We don't want to mark the %r3 as unused even though it's a sub-register of %x3.

c29399e54e - Fix support for "special" i64 immediates that can be loaded 
using IL, ILA, et. al. v2i64 and i64 are now supported by
  the select bits (SELB) instruction.

- Add missing comparison operations (testcase forthcoming)

- More multiclass refactoring.

3c19a3950c - Expand tabs to spaces. 
- select_bits.ll now fully functional now that PR1993 is closed. It was
  previously broken by refactoring in SPUInstrInfo.td and using multiclasses.
- Same for eqv.ll

15cc6fabaf This patch fixes a problem encountered by the CellSPU backend where variants 
were being pruned in patterns where a variable was used more than once, e.g.:

  (or (and R32C:$rA, R32C:$rC), (and R32C:$rB, (not R32C:$rC)))

In this example, $rC is used more than once and is actually significant to
instruction selection pattern matching when commuted variants are produced.
This patch scans the pattern's clauses and collects the variables, creating
a set of variables that are used more than once. TreePatternNode::isIsomorphicTo()
also understands that multiply-used variables are significant.
