[PATCH] D64172: Basic codegen for MTE stack tagging.

[Evgenii Stepanov via Phabricator via llvm-commits]

eugenis updated this revision to Diff 209393.
eugenis added a comment.

Made aarch64.irg.sp IntrInaccessibleMemOnly cause it has side effects.
Simplified SDAG a little by matching intrinsic directly w/o going through an SDag node for IRGstack.
Added a bunch of tests.
