* Eliminate calls to CastInst::createInferredCast.

* Add support for promoting unions with fp values in them. This produces
our new int<->fp bitcast instructions, implementing
Transforms/ScalarRepl/union-fp-int.ll
As an example, this allows us to compile this:
union intfloat { int i; float f; };
float invsqrt(const float arg_x) {
union intfloat x = { .f = arg_x };
const float xhalf = arg_x * 0.5f;
x.i = 0x5f3759df - (x.i >> 1);
return x.f * (1.5f - xhalf * x.f * x.f);
