Make less assumptions about what objects will be available when
vm context creation or error message printing fail because V8
runs out of JS stack space.

Ref: nodejs#6899

Don't cache the exported values of fully uninitialized builtins.
This works by adding an additional `loading` flag that is only
active during initial loading of an internal module and checking
that either the module is fully loaded or is in that state before
using its cached value.

This has the effect that builtins modules which could not be loaded
(e.g. because compilation failed due to missing stack space) can be
loaded at a later point.
