      Track based on JSArrayBuffer addresses instead of the attached backing store.
This way we can later on iterate buffers on a single page. The reland also
switches to a page-based implementation where a page contains the set of its
contained (live and dead) buffers.

Details of tracking:
- Scavenge: New space pages are processes in bulk on the main thread
- MC: Unswept pages are processed in bulk in parallel. All other pages
  are processed by the sweeper concurrently.

      Workaround for glibc semaphore bug. · 84ee9470
      ulan authored 
      Instead of dynamically creating semaphore for each page parallel job,
we create one semaphore for MarkCompact and reuse it.

This patch also removes all instrumentation code that was added to
help with investigation.

      [heap] Get rid of the wrapper in remembered-set.h · 3ddb2249
      ahaas authored 
      This patch moves the wrapper code from the remembered-set to the
scavenger and the mark-compact code.

The wrapper code inspected a slot address to see if the object that
belongs to the address is in the from-space. If it was in the
from-space, then some callback was executed on the object. If the object
got move to the to-space, then the wrapper returned KEEP_SLOT, otherwise
REMOVE_SLOT.

This logic does not really belong to the remembered set, so I moved it
away from there.

      Refactor PointerUpdatingVisitor. · c3a906d5
      ulan authored 
      This patch extracts typed slot processing logic from
the PointerUpdatingVisitor to a set of functions.

Each of these functions takes an untyped slot processing function
and applies it to a typed slot.

      [heap] Uncommit pooled pages concurrently · 2158df87
      mlippautz authored 
      - Move the concurrent unmapping to MemoryAllocator
- Hide (private) members where possible
- MemoryAllocator:Free is now the bottleneck for freeing
- Pooled pages are either allocated from a set of pooled pages are obtained
  through work stealing from the concurrent unmapper
