In reclaimChunk, the runtime is calling traceGCSweepDone() while holding the mheap
lock. traceGCSweepDone() can call traceEvent() and traceFlush(). These functions
not only can get various trace locks, but they may also do memory allocations
(runtime.newobject) that may end up getting the mheap lock. So, there may be
either a self-deadlock or a possible deadlock between multiple threads.
It seems better to release the mheap lock before calling traceGCSweepDone(). It is
fine to release the lock, since the operations to get the index of the chunk of
work to do are atomic. We already release the lock to call sweep, so there is no
new behavior for any of the callers of reclaimChunk.
With this change, mheap is a leaf lock (no other lock is ever acquired while it
is held).
Testing: besides normal all.bash, also ran all.bash with --long enabled, since
it does longer tests of runtime/trace.

may point to unallocated or already dead memory. Most pointer
writes, like the store instructions generated by the compiler,
are already atomic. But we still need to be careful in places
like memmove. In memmove, we don't know which bits are pointers
(or too expensive to query), so we ensure that all aligned
