This revision is now accepted and ready to land.
LGTM. Looking at it it does make me wonder if we should handle things that aren't ConstantInt, e.g.
bitcast <2 x i16> <i16 0, i16 0> to i32
is still zero, though I'm guessing things like this actually probably never happen and this commit is fine as it is anyway.
