Message:

Implement a JIT-code aware sampling profiler for JSC
​https://bugs.webkit.org/show_bug.cgi?id=76855

Rubber stanmped by Geoff Garen.

Mechanical change - pass CodeBlock through to the executable allocator,
such that we will be able to map ranges of JIT code back to their owner.
