dcf193f18c [turbofan] Strength reduction for inline comparisons. 
Perform strength reduction on machine operators with inline comparisons:

  CMP & 1 => CMP
  1 & CMP => CMP
  CMP << 31 >> 31 => CMP

Also strength reduce the following constructs:

  x + (0 - y) => x - y
  (0 - y) + x => x - y

0882d3ff81 [turbofan] Initial version of branch cloning. 
This implements a special case of block cloning to recognize constructs like

 if (a ? b : c) { ... }

that happen to be generated by Emscripten quite often.

87f77d6aba for-of should throw if result object is not an object 
This is done using desugaring. Before this we had:

  result = iterator.next()

with this we instead do:

  !%_IsSpecObject(result = iterator.next()) &&
      %ThrowIteratorResultNotAnObject(result)

36e72aedf0 ES6 collections: Fix order of constructor logic 
The adder should be gotten before the iterator.

Motivation: Once this is done we should be able to use a for-of loop
instead which leads to cleaner code and correct behavior once the
for-of loop correctly supports abrupt completion.

a538d945e3 Teach ModuleDescriptor about basic local exports 
Add() becomes AddLocalExport, which takes an export_name and a local_name.
New parsing tests exercise this.

Also start generating exports for default exports (though this doesn't yet
handle anonymous default exports).

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.

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.
