Bundle conditions checked by UBSan with sanitizer kinds they implement.

Summary:
This change makes CodeGenFunction::EmitCheck() take several
conditions that needs to be checked (all of them need to be true),
together with sanitizer kinds these checks are for. This would allow
to split one call into UBSan runtime into several calls in case
different sanitizer kinds would have different recoverability
settings.

Tests should be fixed accordingly, I'm working on it.

Test Plan: regression test suite.
