[move-only] Fix a small thinko. Specifically, I forgot that when asserts are disabled I made FieldSensitivePrunedLivenessBoundary::getNumLastUsersAndDeadDefs() assert to make sure that callers were sure to place it within a #ifndef block since it is rather expensive and not actual used in the computation. Funnily, I forgot to end. rdar://104107922
