948c50e2be PPC64 passes arguments of integral type in i64 registers, not i32. Reflect this 
by promoting smaller integral values (i32 at this point) to i64, then truncating
to get the wanted size.

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.

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

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.
