* Generalize FP constant shrinking optimization to apply to any vtChris Lattner2008-03-051-0/+7

On x87, it's important to shrink fp constant since fldt is very expensive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47931 91177308-0d34-0410-b5e6-96231b3b80d8

* This is the initial check-in for adding register scavenging to PPC. (Currently,Bill Wendling2008-03-031-2/+2
| | | | | | | | | | | 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).
