History
Chris Lattner fb887e010d Force the intregs ptr into R2 and the FPregs ptr into R3. This fixes a really 
obscure problem where we were doing:

lmw     r3,0(r9)

which is undefined on PPC.  Now we do:

lmw     r3,0(r2)

by force, not relying on the GCC register allocator for luck :)

TODO:
* poor switch statement codegen
* load/store to alloca'd array or struct.
* implement not-R0 register GPR class
* implement scheduling info
* implement do-loop pass
* implement do-loop -> bdnz transform
* implement powerpc-64 for darwin
* implement powerpc-64 for aix
* use stfiwx in float->int
* should hint to the branch select pass that it doesn't need to print the
  second unconditional branch, so we don't end up with things like:
	b .LBBl42__2E_expand_function_8_674	; loopentry.24
	b .LBBl42__2E_expand_function_8_42	; NewDefault
