runtime: define and enforce synchronization on heap_scan Currently heap_scan is mostly protected by the heap lock, but gcControllerState.revise sometimes accesses it without a lock. In an effort to make gcControllerState.revise callable from more contexts (and have its synchronization guarantees actually respected), make heap_scan atomically read from and written to, unless the world is stopped. Note that we don't update gcControllerState.revise's erroneous doc comment here because this change isn't about revise's guarantees, just about heap_scan. The comment is updated in a later change.
