[Sami Tolvanen via Phabricator via cfe-commits]

samitolvanen updated this revision to Diff 440389.
samitolvanen added a comment.

- Moved to a standalone function for generating KCFI type hashes in Clang.
- Switched from pseudo instructions to a `MachineInstr::ExtraInfo` + `SDNode` attributes.
- Added KCFI passes for emitting the indirect call checks.
