Extended Description

The following fails with "llc -march=arm -mcpu=cortex-a9":
define <2 x double> @​a(<2 x i32> %x) nounwind readnone {
entry:
%conv = sitofp <2 x i32> %x to <2 x double>
ret <2 x double> %conv
}

A quick look makes me think it's getting marked legal by accident.

This seems to have been fixed. Works on ToT.
