History
Chris Lattner 051d45ce3c Modify the ISD::AND opcode case to use new immediate constant predicates. 
Includes wider support for rotate and mask cases.

Patch by Jim Laskey.

I've requested that Jim add new regression tests the newly handled cases.

TODO:
* gpr0 allocation
* implement do-loop -> bdnz transform
* implement powerpc-64 for darwin
* use stfiwx in float->int
* be able to combine sequences like the following into 2 instructions:
	lis r2, ha16(l2__ZTV4Cell)
	la r2, lo16(l2__ZTV4Cell)(r2)
	addi r2, r2, 8

* Support 'update' load/store instructions.  These are cracked on the G5, but
  are still a codesize win.

* 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
	b .LBBl42__2E_expand_function_8_42	; NewDefault
