The loop was erasing the user of a value while iterating on the value's users, which results in a use after free. We're already assuming (and asserting) that there's only one user, so we can just access it directly instead. CIR/Transforms/Target/x86_64/x86_64-call-conv-lowering-pass.cpp was failing with ASAN before this change. We're now ASAN-clean except for llvm#829 (which is also in progress).
