It would be nice to have suppression support for UbSAN. It is currently
possible to disable a specific test per compilation unit. But we would like to
suppress certain tests for a specific code line. Either by code annotation or a
separate suppression file. This would allow us to guarantee with
regressiontests that float division by zero and unsigned int overflow is only
used if annotated.
