[PATCH] D76518: [ARM] CMSE code generation

[Momchil Velikov via Phabricator via llvm-commits]

chill updated this revision to Diff 262628.
chill added a comment.
This revision is now accepted and ready to land.

The last version of the patch broke compilation with expensive checks - the machine verifier
reported a score of lifetime errors.
In this update, we are more precise with the RegState flags when creating instructions
to save/restore/clear registers around non-secure calls and before return to non-secure state.
