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.

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.

Original commit message:
This adds a new ControlFlowOptimizer that - for now - recognizes chains
of Branches generated by the SwitchBuilder for a subset of javascript
switches into Switch nodes. Those Switch nodes are then lowered to
either table or lookup switches.

Also rename Case to IfValue (and introduce IfDefault) for consistency.
