[not a change request] `OpenMP_CollapseClause` was removed in #99506 because it become redundant with `OpenMP_LoopRelatedClause`. I see the number of affected loops stored `OpenMP_LoopRelatedClause` (determined by collapse+ordered+sizes) can now diverge from the number of loops collapsed for the workshare/distribute-loop/taskloop constructs. I assume this is why it is re-added.
