eca5b5d7ab Move hash code from hidden string to a private symbol 
* 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%.  After the measurements, I fixed global proxies, which cost 1% on most tests and 5% on the weak ones :-(.

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 lookup to insert it, we could do one lookup and handle the addition immediately).  With the current benchmarks above this buys us nothing, but if we go back to doing more lookups in C++ instead of in stubs and JS then it's a win.

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.

7f4fa3b8f1 Call builtin code wrapped in functions from the bootstrapper. 
For the moment, we only pass the global object (the one we are setting up).
A few smaller changes were necessary to avoid failures in
test-object-observe/DontLeakContextOnObserve. Otherwise the global object
would be retained by being context allocated, leading to test failure.

022ea7e057 [turbofan] Unify Math.floor / Math.ceil optimization. 
Provide an intrinsic %MathFloor / %_MathFloor that is used to optimize
both Math.ceil and Math.floor, and use the JS inlining mechanism to
inline Math.ceil into TurboFan code. Although we need to touch code
outside of TurboFan to make this work, this does not affect the way we
handle Math.ceil and/or Math.floor in CrankShaft, because for CrankShaft
the old-style builtin function id based inlining still kicks in first.

Once this solution is stabilized, we can use it for Math.floor as well.
And once that is settled, we can establish it as the unified way to
inline builtins, and get rid of the specialized builtin function id
based inlining at some point.

Note that "builtin" applies to basically every piece of internal
JavaScript/intrinsics based code, so this also applies to the yet to be
defined JavaScript based code stubs and handlers.
