We can not bitcast pointers across different address spaces. This was previously fixed in D89577 but then in D93229 an enhancement was added which peeks further through the ponter operand, opening up the possibility that address-space violations could be introduced. Instead of bailing as the previous fix did, simply insert an addrspacecast cast instruction. Reviewed By: lebedev.ri Differential Revision: https://reviews.llvm.org/D121787
