[PATCH] D3002: SROA fix to avoid invalid bitcast generation when converting a load from a double pointer bitcasted with an address space change of the pointee pointee

arsenm added a comment.

This same problem was reported here recently and this patch fixes it:

The pointer sizes and formats are incompatible so there isn't really anything sensible to do other than to do this ptrtoint / inttoptr pair, so this makes sense to me.
