Add support for lowering 32-bit/64-bit pointers
Summary:
This follows a previous patch that changes the X86 datalayout to represent
mixed size pointers (32-bit sext, 32-bit zext, and 64-bit) with address spaces
(https://reviews.llvm.org/D64931)
This patch implements the address space cast lowering to the corresponding
sign extension, zero extension, or truncate instructions.
