runtime: record mutex event before readying Currently, semrelease1 readies the next waiter before recording a mutex event. However, if the next waiter is expecting to look at the mutex profile, as is the case in TestMutexProfile, this may delay recording the event too much. Swap the order of these operations so semrelease1 records the mutex event before readying the next waiter. This also means readying the next waiter is the very last thing semrelease1 does, which seems appropriate. Fixes #19139.
