Florian Hahn 0577cdaa32 [LV] Split checking if tail-folding is possible, collecting masked ops. (#77612)
Introduce new canFoldTail helper which only checks if tail-folding is
possible, but without modifying MaskedOps.

Just because tail-folding is possible doesn't mean the tail will be
folded; that's up to the cost-model to decide. Separating the check if
tail-folding is possible and preparing for tail-folding makes sure that
MaskedOps is only populated when tail-folding is actually selected.
