a0bc9eb040 Add more bailouts for Array.slice over arguments.
Unfortunately, arguments is pretty much the normal JS object.  For now
I am adding more sanity checks (in hope that typically arguments
list is rather short.)  However it probably requires more systematic
treatment, for example, we could optimistically copy elements until
we meet first hole and in this case resort to JS builtin.

ae476ecd6c Teach C++ ArraySlice builtin to deal with arguments object.
Array.prototype.slice.call(arguments, ...) idiom is pretty common (up to 97% of invocations
in GMail), so we'd better handle it efficiently too.

e8e35eccac Properly process arrays with overridden prototype in various Array's functions.
Bailout to JS Array builtins if array's prototype is different from
Array.prototype.  Otherwise there might be inherited elements coming
from this prototype.
