Unfortunately I don't see any difference after the patch, either applied on rG3cef3cf02f09e397c471cf008060c89b34951959 <https://reviews.llvm.org/rG3cef3cf02f09e397c471cf008060c89b34951959> or on ToT. The repro still don't emit the `mov`s into the target buffer. Is anyone able to confirm?

When I tested this I dropped the `__attribute__((malloc))` from the preprocessed source, and that did it for me. Note that this patch needs to be in the source code for the stage2 lld build, not the stage1 clang build.
