Thread safety analysis: Eliminate parameter from intersectAndWarn (NFC)

Authored by aaronpuchert on May 3 2021, 5:06 AM.



We were modifying precisely when intersecting the lock sets of multiple
predecessors without back edge. That's no coincidence: we can't modify
on back edges, it doesn't make sense to modify at the end of a function,
and otherwise we always want to intersect on forward edges, because we
can build a new lock set for those.
