00a1951fb1 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.

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
