OccurAnal: Ensure SourceNotes don't interfere with join-point analysis
In general ticks are problematic for join point analysis as described
in #14242. However, source notes are intended to be a best-effort
annotation which shouldn't interfere with optimization. Special-case
these to ensure that tail-call information is still correct, even in the
presence of source note
ticks.
