Chris Lattner 408fee7ad4 evan's recent x86 isel improvements have fixed this, though not in the way 
originally envisioned :)

Chris Lattner b9f35f06bc Add a subtarget feature for the stfiwx instruction. I know the G5 has it, 
but I don't know what other PPC impls do.  If someone could update the proc
table, I would appreciate it :)

Chris Lattner bdbc4476d9 Fold "and (LOAD P), 255" -> zextload. This allows us to compile: 
unsigned foo3(unsigned *P) { return *P & 255; }

        lbz r3, 3(r3)
        blr

instead of:

_foo3:

        rlwinm r3, r2, 0, 24, 31

Chris Lattner c7bfed0f7b Merge two almost-identical pieces of code. 
Make this code more powerful by using ComputeMaskedBits instead of looking
for an AND operand.  This lets us fold this:

int %test23(int %a) {
        %tmp.1 = and int %a, 1
        %tmp.2 = seteq int %tmp.1, 0
        %tmp.3 = cast bool %tmp.2 to int  ;; xor tmp1, 1
        ret int %tmp.3
}

into: xor (and a, 1), 1
