<pre>We should teach UBSan to:
1) read suppressions from __ubsan_default_suppressions() like we do in ASan,
LSan and TSan.
2) allow to suppress specified kind of UB (e.g. "signed-integer-overflow") in
specified source locations (e.g. source locations). For now we can only exclude
certain types from vptr checks.
Of course, the suppressions will only work if the error kind is specified to be
recoverable at compile-time.</pre>
