Use a PowerPC specific prolog epilog inserter to control where spilled callee save regs are placed on the stack. Get rid of implicit return address stack slot, save return address reg (LR) in appropriate slot Improve code generated for functions that don't have calls or access globals Note from Chris: PowerPCPEI will eventually be eliminated, once the functionality is merged into CodeGen/PrologEpilogInserter.cpp git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15536 91177308-0d34-0410-b5e6-96231b3b80d8
