152dbbe856 Remove 64 bit simple ISel, it never worked correctly 
Add initial (buggy) implementation of 64 bit pattern ISel

833c1d0994 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

0e77845b7e 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.

c4abcbefb1 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

f2c87f4794 Disable PPC64 backend by default because LLC cannot choose automatically between 
SparcV9 and PowerPC64 without target triples, since they are both 64-bit
big-endian targets.

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

53dc31efcd Do IMPLICIT_DEFs on incoming args' hard regs, to avoid confusing the regalloc. 
Support single-fp incoming args.
Support single-fp outgoing args ('call' operands).

b755d35fd2 Change MachineBasicBlock's vector of MachineInstr pointers into an 
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.
