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.

7c15df8144 [strong] Remove mjsunit/strong/use-strong-flag.js 
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.

acd9c46ca7 [turbofan] Optimize certain chains of Branch into a Switch. 
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.
