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
type (e.g. we get v4f32 instead of v8i16). Make sure to convert the vector
result to the right type. This fixes CodeGen/X86/2007-04-11-InlineAsmVectorResult.ll
