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.

- Clean up the lowering and selection code of ConstantPool, GlobalAddress,
...
and ExternalSymbol.
- Use C++ code (rather than tblgen'd selection code) to match the above
mentioned leaf nodes. Do not mutate and nodes and do not record the
selection in CodeGenMap. These nodes should be safe to duplicate. This is
a performance win.
