[PATCH] D148316: [AArch64] Add support for efficient bitcast in vector truncate store.

Added check for illegal types. I could not get this check to actually fire. The type is legalized before the bitcast in the bitcast lowering case, and it is legalized before the 
store becomes a truncating store. So in both cases other checks prevent bad things from happening. But it is probably still fine to keep it as a defensive check in case things 
change.
