A few tests fails when I run them with --hydrogen-track-positions
...
The root of problem is the fact that we don't track the position of 'this' statement but use them when visit compare statement.
As a result we have -1 as the position of left expression and the resulting relative position is negative and doesn't fit into BitField.

Rename Interface to ModuleDescriptor
...
ModuleDescriptor will end up holding the set of data described in the
spec as a "Module record". This introduces a little bit of confusion
with ModuleInfo, but I hope that'll become clearer over time.
Also removed the interface-printing flags. We probably want
Module-printing flags, but that can wait until we have more
Module-related structures.

Strip Interface class of most of its logic, make it all about Module exports

This gets Variable and VariableProxy out of the business of worrying about
Interfaces.
At the same time, get rid of the notion of "module variables". In ES6, variables
that refer to modules will be simply be CONST bindings to module namespace
objects.
The only change in logic here is one more early error:
duplicate export names are now rejected.
