Additionally handlify the "transition" field so that GC can stop caring about it.

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.

It would force us to make mjsunit.js strong-compatible, and that's too much for
now (for the upcoming features) and would have a ripple effect on other
tests. Especially debug-script.js which unships harmony features would break.

Fix compilation problem with android toolchain.
Added new INTERNAL_REFERENCE_ENCODED RelocInfo type to differentiate MIPS existing use of internal references in instructions from the new raw pointer reference needed for dd(Label*).

A function could be deoptimized due to a deopt in the inlined code.
The inlined function might be defined in another script. So we need to
track the information about the inlined functions (scriptId and offset).
We already have the tracking code which is behind FLAG_hydrogen_track_position.
So as the first step we need to make the info accessible by CPU profiler.
In the follow-up patches I'll add the code which will enable position
tracking and push the info into CodeEntry entries.
