Provide support for intrinsics that lower themselves to a function body.

This can happen for intrinsics that are overloaded. In such cases it is
necessary to emit a function prototype before the body of the function
that calls the intrinsic and to ensure we don't emit it multiple times.

the result of an inline asm copy can be an arbitrary VT that the register

class supports. In the case of vectors, this means we often get the wrong
