[debugger] break on sanitizer error

i often find myself trying to debug code when running address sanitizer or undefined sanitizer.

the "add breakpoint" dialog has a few handy shortcuts to e.g. break when an exception is thrown. it would be very convenient to have another option to "break on sanitizer error".

some heuristics on how to break are listed in https://stackoverflow.com/questions/30809022/how-can-i-break-on-ubsan-reports-in-gdb-and-continue ... of course one can do that manually, but it would be a nice convenience feature if qt-creator had a shortcut for this
