Nate Begeman dabf0a52c0 Fix frame pointer handling: 
Reserve R0 in store/load from stack slot for building >32k offsets from SP
or FP.  This also requires we use R11 rather than R0 for holding the LR
value we want to save or restore.  Also, tell the register allocator not
to use R31 (our FP) in functions that have a frame pointer.  These changes
fix Burg.

Chris Lattner 7dfaac4300 Zimm16 is now dead. Its entry is not removed from the enum, to avoid having 
to renumber everything.  Similar elimination should be applied to other

Reid Spencer 42817b7ea1 Fix stack size processing now that the return address isn't an implied

Chris Lattner a8dcf2423e 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
