I believe that as a bitcast is defined as a store+load, we end up with `store(oldtype); load(newtype); store(newtype)`, which should be endian safe. GISel doesn't handle BE yet though, so it probably isn't possible to test.

As far as I understand, Chuong was having a go at changing this to use bitcastIf instead of doing it in a custom method.
