[PATCH] D120026: [ARM] Fix ARM backend to correctly use atomic expansion routines.

[Joerg Sonnenberger via Phabricator via llvm-commits]

joerg added a comment.

I'm ambivalent about wether to use __sync_* or __atomic_*, but last time I looked at this, we generated the generic unsized variant a lot, even when the arguments have a known static size.
