e24c612a5e Fix setting array length to be ES5 conform.
This also refactors the way we set the length of an arrays' backing
store to use the new elements accessor interface. The actual fix is in
DictionaryElementsAccessor::SetLengthWithoutNormalize() where we first
search for non-deletable elements according to ES5 section 15.4.5.2
specifications.

Snippet from the specification: Attempting to set the length property of
an Array object to a value that is numerically less than or equal to the
largest numeric property name of an existing array indexed non-deletable
property of the array will result in the length being set to a numeric
value that is one greater than that largest numeric property name.

As for 'let' bindings, the semantics of 'const' bindings in global scope is not

6742176949 Fix Array.filter to use internal array for result.

possible to affect the built-in code by putting getters or setters on
the array prototype chain. Using internal arrays prevents those issues.
