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
set.  This is done to avoid creating invalid UTF-8 output which can lead to
compatibility issues with software requiring valid UTF-8 inputs (e.g. the
WebSocket protocol requires valid UTF-8 and terminates connections when invalid
UTF-8 is encountered).

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.

Recent changes in IC logic meant that CallStubs no longer use the Contextual bit. IsUndeclaredGlobal() needed to adjust for that.

In fact, now the CL has morphed to remove the notion of storing contextual state in the IC at all, it just becomes some extra ic state of the load ic. This took some adjustment in harmony code to use the global receiver for certain stores.

Now it's clearer that only LoadICs actually record any information about contextual or not.

When invoking a setter callback for a property using
JSObject::SetPropertyWithCallback(),the callback arguments includes
a correct pair of receiver and holder objects.

Such a pair of _possibly different_ arguments (receiver, holder) must
also be supplied when invoking the same setter callback from JITed
code, when the setter is invoked through the StoreCallbackProperty
stub.

An example where this matters are the accessor properties kept on the
global scope of Worker (i.e., properties kept on the global object
itself, and not on its prototype.) Conflating the receiver with the
holder leads to general confusion when attempting to fetch out the
wrapper object.
