Original commit message:
In a nutshell: The FILTER_KEY builtin is gone, and was replaced by a
simple runtime call to ForInFilter, which does everything and is even
cheaper (because FILTER_KEY used to call into the runtime anyway).
And ForInFilter returns either the name or undefined, which makes it
possible to remove the control flow construction from the AstGraphBuilder,
and thereby make both the initialization and the per-loop code of for-in
optimizable later (in typed lowering).

This is basically a port of the majority of optimizations that are
applied to for-in in full codegen. But it is not done during graph
building, but instead during typed lowering, which way less adhoc than
what the other compilers do.

Implements the strong mode proposal's restrictions on the behaviour of the

Setting the strong bit is still wip, so this change will only affect those
objects that have the bit correctly set. The tests reflect this, and will be
expanded as more objects can be marked as strong.

port eca5b5d7 (r28622).

original commit message:

   * Hash code is now just done with a private own symbol instead of the hidden string, which predates symbols.
    * In the long run we should do all hidden properties this way and get rid of the
    hidden magic 0-length string with the zero hash code.  The advantages include
    less complexity and being able to do things from JS in a natural way.
    * Initially, the performance of weak set regressed, because it's a little harder
    to do the lookup in C++.  Instead of heroics in C++ to make things faster I
    moved some functionality into JS and got the performance back. JS is supposed to be good at looking up named properties on objects.
    * This also changes hash codes of Smis so that they are always Smis.

    Performance figures are in the comments to the code review.  Summary: Most of js-perf-test/Collections is neutral.  Set and Map with object keys are 40-50% better.  WeakMap is -5% and WeakSet is +9%.

    In the code review comments is a patch with an example of the heroics we could do in C++ to make lookup faster (I hope we don't have to do this.  Instead of checking for the property, then doing a new

    In a similar vein we could give the magic zero hash code to the hash code
    symbol.  Then when we look up the hash code we would sometimes see the table
    with all the hidden properties.  This dual use of the field for either the hash
    code or the table with all hidden properties and the hash code is rather ugly,
    and this CL gets rid of it.  I'd be loath to bring it back.  On the benchmarks quoted above it's slightly slower than moving the hash code lookup to JS like in this CL.

    One worry is that the benchmark results above are more monomorphic than real
    world code, so may be overstating the performance benefits of moving to JS.  I
    think this is part of a general issue we have with handling polymorphic code in
    JS and any solutions there will benefit this solution, which boils down to
    regular property access. Any improvement there will lift all boats.
