[PATCH] [UBSAN] Suppress an error report with given type information

[Alexey Samsonov]

The problem could be difference in environment options. E.g. UBSan+ASan tests setup ASAN_OPTIONS=detect_leaks=0 (which overrides the default). Note that it is important, as LSan also supports suppressions, and creates/parses suppression context only if detect_leaks is setup to true.
