Cleanup stack/frame register define/kill states. This fixes two bugs: 1. The ST*UX instructions that store and update the stack pointer did not set define/kill on R1. This became a problem when I activated post-RA scheduling (and had incorrectly adjusted the Frames-large test). 2. eliminateFrameIndex did not kill its scavenged temporary register, and this could cause the scavenger to exhaust all available registers (and its emergency spill slot) when there were a lot of CR values to spill. The 2010-02-12-saveCR test has been adjusted to check for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147359 91177308-0d34-0410-b5e6-96231b3b80d8

Do not store R31 into the caller's link area on PPC. This violates the ABI (that area is "reserved"), and while it is safe if all code is generated with current compilers, there is some very old code around that uses that slot for something else, and breaks if it is stored into. Adjust testcases looking for current behavior. I've verified that the stack frame size is right in all testcases, whether it changed or not. 7311323. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89811 91177308-0d34-0410-b5e6-96231b3b80d8
