runtime: get tracking time only when needed
casgstatus currently calls nanotime on every casgstatus when tracking,
even though the time is only used in some cases. For goroutines making
lots of transitions that aren't covered here, this can add a small
overhead. Switch to calling nanotime only when necessary.
