rts: Tracing support for nonmoving collection events
This introduces a few events to mark key points in the nonmoving
garbage collection cycle. These include:
* `EVENT_CONC_MARK_BEGIN`, denoting the beginning of a round of
marking. This may happen more than once in a single major collection
since we the major collector iterates until it hits a fixed point.
* `EVENT_CONC_MARK_END`, denoting the end of a round of marking.
* `EVENT_CONC_SYNC_BEGIN`, denoting the beginning of the post-mark
synchronization phase
* `EVENT_CONC_UPD_REM_SET_FLUSH`, indicating that a capability has
flushed its update remembered set.
* `EVENT_CONC_SYNC_END`, denoting that all mutators have flushed their
update remembered sets.
* `EVENT_CONC_SWEEP_BEGIN`, denoting the beginning of the sweep portion
of the major collection.
* `EVENT_CONC_SWEEP_END`, denoting the end of the sweep portion of the
major collection.
