eliminateFrameIndex() has been reworked to handle both small & large frames with either a FP or SP. An additional Slot is required for Scavenging spills when not using FP for large frames. Reworked the handling of Register Scavenging. Whether we are using an FP or not, whether it is a large frame or not, and whether we are using a large code model or not are now independent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196091 91177308-0d34-0410-b5e6-96231b3b80d8
