5e9666129a Implement more of the PPC32 Pattern ISel: 
1) dynamic stack alloc
2) loads
3) shifts
4) subtract
5) immediate form of add, and, or, xor
6) change flag from -pattern-isel to -enable-ppc-pattern-isel

Remove dead arguments from getGlobalBaseReg in the simple ISel

a9795f81e9 Addition of the PPC32 Pattern ISel. While it is far from complete, it will 
be brought up to parity with the current simple ISel in the coming days.
Currently, -pattern-isel is required to trigger it.

3ea934668b 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
