7fc3fd76e3 Re-enable test-api/RegExpInterruption on arm. 
This test has been disabled for a very long time, and the fix in
http://code.google.com/p/v8/source/detail?r=5308 should make this go
away.

I will watch the buildbot continuously over the next few days to make
sure it does not appear again. If it does not I will close bug 240.

2982f5e320 Change code pointer in function objects to a pointer to the first 
instruction.

By changing the pointer to the code object to a pointer to the first
instruction we can call directly this instruction directly instead of
looking up the address through the code object.

3202df6c69 Copy-on-write arrays. 
Object model changes
----------------------------------------
New fixed_cow_array_map is used for the elements array of a JSObject
to mark it as COW. The JSObject's map and other fields are not
affected. The JSObject's map still has the "fast elements" bit set. It
means we can do only the receiver map check in keyed loads and the
receiver and the elements map checks in keyed stores. So introducing
COW arrays doesn't hurt performance of these operations. But note that
the elements map check is necessary in all mutating operations because
the "has fast elements" bit now means "has fast elements for reading".
EnsureWritableFastElements can be used in runtime functions to perform
the necessary lazy copying.

Generated code changes
----------------------------------------
Generic keyed load is updated to only do the receiver map check (this
could have been done earlier). FastCloneShallowArrayStub now has two
modes: clone elements and use COW elements. AssertFastElements macro
is added to check the elements when necessary. The custom call IC
generators for Array.prototype.{push,pop} are updated to avoid going
to the slow case (and patching the IC) when calling the builtin should
work.

COW enablement
----------------------------------------
Currently we only put shallow and simple literal arrays in the COW
mode. This is done by the parser.

5cd4a9b78d Remove runtime function from fuzzing 
Don't do fuzzing of _IsStringWrapperSafeForDefaultValueOf as it expects a non-smi as its first argument.

8e0cd6db8a Handle overwriting valueOf on String objects correctly when adding 
This adds a check to the fast case string add to ensure that the String object still have the default valueOf function. The default valueOf is sitting on a hidden prototype of String.prototype.

Before using the fast case valueOf the object is checked for a local valueOf property. For slow case objects this check always reports true (the dictionary is not probed, so valueOf might be there) and for fast case objects the descriptor array is checked for the valueOf symbol (just liniar scan). After that the prototype is checked for beeing the initial value of String.prototype. If this all pass (that is the default valueOf is still in place) this result is cached on the map making the check fast the next time.

This is only implemented in the optimizing compiler, as the two usages of %_IsStringWrapperSafeForDefaultValueOf is never hit by the full compiler.

I will port to x64 and ARM when this has been reviewed for ia32.

I will remove the performance counters prior to final commit.
