8bf21cd984 Fix stack size processing now that the return address isn't an implied 
push onto the top of the stack like x86, which uses the local area
offset.  This will allow the removal of PowerPCPEI.cpp soon.

bbf11b1e1d Changes commited for Nate Begeman: 
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
