[CodeGen] fix test to be (mostly) independent of LLVM optimizer; NFC

This test would break with the proposed change to IR canonicalization
in D79171. The raw unoptimized IR from clang is massive, so I've
replaced -instcombine with -mem2reg to make it more manageable,
but still be unlikely to break with unrelated changed to optimization.
