   Add an MSan based sanitizer job, for a number of reasons:

   • Does something memcheck (valgrind) like, but can also run on macOS (even post #1152), which can be added as a follow-up.
   • We could extend to ctime testing to work on this instead (meaning against ctime testing, with some limitations, can be re-enabled on macOS post #1152).

   O3 is a nice idea! we should do this for some other jobs too.

   (In another PR – I added a note in #707 (comment))
