Compile this:
...
void foo(float a, int *b) { *b = a; }
to this:
_foo:
fctiwz f0, f1
stfiwx f0, 0, r4
blr
instead of this:
_foo:
fctiwz f0, f1
stfd f0, -8(r1)
lwz r2, -4(r1)
stw r2, 0(r4)
blr
This implements CodeGen/PowerPC/stfiwx.ll, and also incidentally does the
right thing for GCC bugzilla 26505.
