33d7e64b51 ES6: Implement Object.setPrototypeOf
This reverts commit bdc89ae76c15f3ef2626f8849744500248aec3ba.

This is a revert of the revert with test/webkit updated as needed.

Original CL Description:

http://people.mozilla.org/~jorendorff/es6-draft.html#sec-object.setprototypeof

This just exposes the internal %SetPrototype and adds all the required
type checks as specified.

b4949cfd62 Fixed floor-of-div optimization.
We removed an HDiv by hand which was still used by an HChange. The
solution is letting dead code removal do the cleanup.

Removed a fragile "optimization" (looking through an HChange), too,
this obviously never triggered and is hard to get right given all our
global invariants and state/type/... changes.

The repro is a bit tricky, because you need inlining to make our
representations and types disagree in this case.

The Array constructor has a needless dependency on an input argument
that is a Cell. It uses this to walk through to an AllocationSite.
The dependency hampers future work. Instead, pass the AllocationSite
as input to the Array constructor.

6eb9e02b00 DoubleToIStub can't use ip on armv6, because the ubfx impl will clobber it
This previous change broke DoubleToIStub on armv6:
https://code.google.com/p/v8/source/detail?r=16322

The problem is that DoubleToIStub::Generate assumed that it could safely use the ip register, but on armv6 the ubfx implementation will clobber any previous value stored there.  So instead, pick another register.

Test case:
for (var i=0; i<2; i++) {
	v = 4294967295;
	v &= -2;
	print(v)
	}

This should print -2 twice, but on armv6 without this patch, it prints -2 followed by 2046.

This problem causes sunspider's bitops-nsieve-bit, crypto-md5 and crypto-sha1 tests to generate incorrect results (but the results are not checked for validity in sunspider-1.0 as available in chromium, but are checked and reported as incorrect in sunspider-1.0.2).

Thanks to Tomasz Kilarski for helping out with this.

This patch makes String::WriteUtf8 replace invalid code points (i.e. unmatched
surrogates) with the unicode replacement character when REPLACE_INVALID_UTF8 is

compatibility issues with software requiring valid UTF-8 inputs (e.g. the
WebSocket protocol requires valid UTF-8 and terminates connections when invalid

0757d56057 De-virtualize GenerateNameCheck.
Currently there are two kinds of "vtables" used in the load/store stub
compilers: kind() and C++'s own vtables. This is a bit confusing, and
this is a step towards simplifying things.

b2bea46245 Minor bugfix in building inlined Array: bad argument to JSArrayBuilder.
An HConstant pointing to a Cell rather than an AllocationSite
was passed. The argument wasn't used because of fortuitous
flags. An assert was added to protect the argument.
