[PATCH] D135652: [AArch64] Add preserve_all calling convention.

[Aaron Ballman via Phabricator via llvm-commits]

aaron.ballman added a comment.

Precommit CI found a relevant issue. Also, can you add release notes to Clang for the improvement?

Also, is there a reason to support `preserve_all` but not `preserve_most` given their relationship?
