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

- 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

1) Literal::IsNull, IsTrue and IsFalse were dead code, and not needed.
2) No need to use the node type constants outside the Ast; there is IsSomeNodeType().
3) AsSomeNodeType() != NULL -> IsSomeNodeType().

This restructures the L1 deopt jump table so that the base address of
the L2 table is only loaded once. This significantly reduces the size of
the generated code because only one big immediate needs to be loaded.

The total size of all L1 deopt tables generated during Octane is almost
halved in size, from about 1105kB to 584kB.

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.
