Make several cleanups to Andrews varargs change:
...
1. Pass Value*'s into lowering methods so that the proper pointers can be
added to load/stores from the valist
2. Intrinsics that return void should only return a token chain, not a token
chain/retval pair.
3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone.
4. Now that we have Value*'s available in the lowering methods, pass them
into any load/stores from the valist that are emitted

Handle some more real world cases of rlwimi. These don't come up that
...
regularly in "normal" code, but for things like software graphics, they
make a big difference.
For the following code:
unsigned short Trans16Bit(unsigned srcA,unsigned srcB,unsigned alpha)
{
unsigned tmpA,tmpB,mixed;
tmpA = ((srcA & 0x03E0) << 15) | (srcA & 0x7C1F);
tmpB = ((srcB & 0x03E0) << 15) | (srcB & 0x7C1F);
mixed = (tmpA * alpha) + (tmpB * (32 - alpha));
return ((mixed >> 5) & 0x7C1F) | ((mixed >> 20) & 0x03E0);
}
We now generate:
_Trans16Bit:
.LBB_Trans16Bit_0: ; entry
andi. r2, r4, 31775
rlwimi r2, r4, 15, 7, 11
