e758a36b02 Clear Map::constructor to object_function from the same context for prototype maps. This avoids keeping small pockets of memory alive for the common pattern where prototypes are used to emulate classes: 
function inherit(parent, child) {
  function p() {}
  p.prototype = parent.prototype;
  child.prototype = new p();
}

Otherwise child.prototype[constructor] keeps alive p, p's context, the
initial map attached to p, and the (now empty) transition array of the
initial map.

36ed9ca348 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.

27e8a455df 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.

522937cb49 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.

97a4a21a6a MIPS: [turbofan] Optimize certain chains of Branch into a Switch. 
Port acd9c46ca7

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.
