Native setters (see AccessorInfo in accessors.h) didn't have the ability
to return a result value. As a consequence of this, for instance, Reflect.set
on the length property of arrays had the wrong behavior:
var y = [];
Object.defineProperty(y, 0, {value: 42, configurable: false})
Reflect.set(y, 'length', 0)
The Reflect.set call used to return true. Now it returns false as
required by the spec.

With the Indexed/GenericNamedPropertyDefinerCallback it is possible to intercept Object.defineProperty() calls.
Requests that call JSReceiver::OrdinaryDefineOwnProperty() internally, also trigger the interceptor. This includes Object.freeze(), Object.preventExtensions(), and Object.seal().
As without this patch, the query interceptor triggers on
defineProperty, unless the definer callback
intercepts the request.

This avoids the inclusion of inline headers (i.e. vm-state-inl.h in this
case) in a normal header. There are three more such violations left in
the code-base after this change.

Passing in the isolate and pointer compare the instnance against the
corresponding constant is always faster than decoding the instance types.

By fully annotating the API with runtime counters we can properly measure
how much time we spend in total in v8. When --runtime-call-stats is specified
we now disable the fast-paths for callbacks to properly measure them.
As a drive-by-fix this CL unifies the LOG messages in api.cc.
Additionally we added missing timers to gain better resolution in the parser
and callbacks.
