* In promote32, if we can just promote a constant value, do so instead of
promoting a constant dynamically.
* In visitReturn inst, actually USE the promote32 argument that takes a
Value*
The end result of this is that we now generate this:
test:
mov %EAX, 0
ret
instead of...
test:
mov %AX, 0
movzx %EAX, %AX
ret
for:
ushort %test() {
ret ushort 0
}
