[PATCH] D65422: [GlobalISel][AArch64] Add naive selection for @llvm.aarch64.ldaxr

[Jessica Paquette via Phabricator via llvm-commits]

I'd prefer to do this by extending the emitter. After D65756 <https://reviews.llvm.org/D65756> lands, we should be able to get the 64-bit load intrinsics this way.

However, we won't be able to get the smaller ones, since their patterns use SUBREG_TO_REG. The emitter doesn't know how to support that yet.
