Fold constant adds into loads and stores to frame indices.
...
For the following code:
double %ext(int %A.0__, long %A.1__) {
%A_addr = alloca %typedef.DComplex ; <%typedef.DComplex*> [#uses=2]
%tmp.1 = cast %typedef.DComplex* %A_addr to int* ; <int*> [#uses=1]
store int %A.0__, int* %tmp.1
%tmp.2 = getelementptr %typedef.DComplex* %A_addr, int 0, uint 1 ; <double*> [#uses=2]
%tmp.3 = cast double* %tmp.2 to long* ; <long*> [#uses=1]
store long %A.1__, long* %tmp.3
%tmp.5 = load double* %tmp.2 ; <double> [#uses=1]
ret double %tmp.5
}
We now generate:
_ext:
.LBB_ext_0: ;
stw r3, -12(r1)
stw r4, -8(r1)
stw r5, -4(r1)
lfd f1, -8(r1)
blr
Instead of:
_ext:
.LBB_ext_0: ;
stw r3, -12(r1)
addi r2, r1, -12
stw r4, 4(r2)
stw r5, 8(r2)
lfd f1, 4(r2)
blr
This also fires hundreds of times on MultiSource.

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
