Some performance sensitive paths in V8 (compilation/json parsing) or
paths with high allocation/freeing throughput can suffer from not being
able to reuse recently freed allocations. These paths can also
significantly increase the working set and cause large number of page
faults. For such paths (at least as an initial measure) we are planning
to disable allocation quarantining.

The CL provides a way for the embedder to hook in *Scan functions that
disable/enable quarantining. It also disables *Scan for json parsing and
compilation jobs.
