LSRA: remove last uses only at use point

LSRA maintains liveness within a block to determine what's live across a call. It uses the last use bits on lclVar nodes to remove them from the set. However, this should be done at the point of use rather than at the point where the lclVar is encountered in the execution stream.

Fix #17389
