a555be2e45 worker: improve MessagePort performance 
Use a JS function as the single entry point for emitting `.onmessage()`
calls, avoiding the overhead of manually constructing each message
event object in C++.

                                                                             confidence improvement accuracy (*)   (**)  (***)

Also fix handling exceptions returned from `MessagePort::New`.

lib: flatten access to primordials 
Store all primordials as properties of the primordials object.
Static functions are prefixed by the constructor's name and prototype
methods are prefixed by the constructor's name followed by "Prototype".
For example: primordials.Object.keys becomes primordials.ObjectKeys.

08a9c4a996 bootstrap: delay the instantiation of maps in per-context scripts 
Instantiating maps renders the snapshot non-rehashable
(v8 currently fails silently during `CreateBlob()`).
Then the hash seed would always be the same and not
recomputed if custom V8 snapshot is enabled. This patch
delays the instantiation of the maps in domexception.js
and make it lazy.
