b58a08d998 Fix PathTracer. 
When tracing, we abuse the map for marking, thereby mutating it.
HeapObject::map() takes care of recovering unabused value.

56a486c322 Use full include paths everywhere 
- this avoids using relative include paths which are forbidden by the style guide
- makes the code more readable since it's clear which header is meant
- allows for starting to use checkdeps

60a71d8a8c Remove PROHIBITS_OVERWRITING as it is subsumed by non-configurable properties. 
v8::DontDelete is set for Unforgeable properties, so just not setting PROHIBITS_OVERWRITING should be enough.

The secondary "feature" of not allowing accessors to be installed in extending objects is incorrect and confusing, given that it only applies to accessors but not to regular properties:
Object.defineProperty({__proto__:window}, "location", { value: 10 })
works where
Object.defineProperty({__proto__:window}, "location", { get: function() {} })
doesn't work.

The change relative to the previous CL is a logic change in
DropActivationsInActiveThreadImpl.  The previous CL skipped the matcher
unless the frame was a JS frame; this was correct for
MultipleFunctionTarget but not for SingleFrameTarget.

I have not been able to reproduce the original failures on either
architecture (ia32 or x64; stack frame dropping is unsupported on other
architectures).

70c3a714a1 ES6 Map/Set iterators/forEach improvements 
This changes how Map/Set interacts with its iterators. When the
underlying table is rehashed or cleared, we create a new table (like
before) but we add a reference from the old table to the new table. We
also add an array describing how to transition the iterator from the
old table to the new table.

When Next is called on the iterator it checks if there is a newer table
that it should transition to. If there is, it updates the index based
on the previously recorded changes and finally changes itself to point
at the new table.

With these changes Map/Set no longer keeps the iterators alive. Also,
as before, the iterators keep the underlying table(s) alive but not the
actual Map/Set.

3274485c50 Store JSGlobalProxy's identity hash directly on the proxy itself 
Previously, the hash was stored on the underlying global object, since
it was stored in the hidden property table. This patch moves to an
implementation modeled on JSProxy, adding a new 'hash' field to JSGlobalProxy.

This allows storing the global proxy in a Map, Set, WeakMap, or WeakSet and
accessing it even after the proxy has been attached to a new global, which
is Firefox's current behavior and was the consensus of a recent thread on public-script-coord:
