patch 9.1.0816: tests: not clear what tests cause asan failures

Problem:  tests: not clear what tests cause asan failures
Solution: append testname to $ASAN_OPTIONS

Mention what test causes ASAN failures by appending the testname
to log_path in $ASAN_OPTIONS/$UBSAN_OPTIONS. This assumes 'log_path' is
always the last sub-option in $ASAN_OPTIONS.

While at it, also make the CI run with `-O0` instead of `-O1` when ASAN
is enable since this causes line numbers to disappear.

closes: #15927
