Scott Michel 42f56b4838 - 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.

Evan Cheng 0a62cb44ce Add a target lowering hook to control whether it's worthwhile to compress fp constant. 
For x86, if sse2 is available, it's not a good idea since cvtss2sd is slower than a movsd load and it prevents load folding. On x87, it's important to shrink fp constant since fldt is very expensive.

Evan Cheng 6325446666 Refactor code. Remove duplicated functions that basically do the same thing as 
findRegisterUseOperandIdx, findRegisterDefOperandIndx. Fix some naming inconsistencies.

this doesn't work yet.  No functional change.

Bill Wendling 632ea65072 This is the initial check-in for adding register scavenging to PPC. (Currently, 
PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that
it uses a register other than the default R0 register (the scavenger scrounges
for one). A significant part of this patch fixes how kill information is
handled.
