Don't assert that no incremental marking happened during a non-incremental GC
...
If a scavenge is triggered during the GC (via a weak callback or the GC
prologue/epilogue), and another mark-compact is triggered (via the same
unfortunate code path), we end up doing some incremental steps.

This is first step towards adding V8 heap statistics to the memory

more information about the heap. So, this Cl extends the api to give
information about the memory allocated and used in the spaces.
