[ubsan] Connect -fsanitize-skip-hot-cutoff to LowerAllowCheckPass<cutoffs> (#124857)
This adds the plumbing between -fsanitize-skip-hot-cutoff (introduced in
https://github.com/llvm/llvm-project/pull/121619) and
LowerAllowCheckPass<cutoffs> (introduced in
https://github.com/llvm/llvm-project/pull/124211).
The net effect is that -fsanitize-skip-hot-cutoff now combines the
functionality of -ubsan-guard-checks and
-lower-allow-check-percentile-cutoff (though this patch does not remove
those yet), and generalizes the latter to allow per-sanitizer cutoffs.
Note: this patch replaces Intrinsic::allow_ubsan_check's
SanitizerHandler parameter with SanitizerOrdinal; this is necessary
because the hot cutoffs are specified in terms of SanitizerOrdinal
(e.g., null, alignment), not SanitizerHandler (e.g., TypeMismatch).
Likewise, CodeGenFunction::EmitCheck is changed to emit
allow_ubsan_check() for each individual check.
