History
Nate Begeman 91ef127999 Kill casts from integer types to unsigned byte, when the cast was only used 
as the shift amount operand to a shift instruction.  This was causing us to
emit unnecessary clear operations for code such as:
int foo(int x) { return 1 << x; }

TODO:
* implement not-R0 register GPR class
* fix rlwimi generation to be use-and-def
* implement scheduling info
* 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
