- Only emit flag when GlobalMerge is disabled (per Akira and Duncan's reviews)
I added a target check to only emit the flags on ARM/AArch64. I'm fine with emitting the flag no matter the target, if desired (less brittle), but I personally don't like adding noise to every module ever, hence hiding it.
