Check the return value of API calls on ia32 and x64.

This implies that the return value of native getters is checked. The nice part
is that one can even see the name of the property in question in the abort
output when the check failed.

Under some circumstances even the return value of interceptors gets checked, but
I'm not 100% sure about this, because the interceptor code is basically tuned to
death.

The change seems to have very low overhead, so it might be feasible to keep this
check enabled unconditionally.

Allocate block-scoped global bindings to global context.

- The global object has a reference to the current global scope chain.
  Running a script adds to the chain if it contains global lexical declarations.
- Scripts are executed relative to a global, not a native context.
- Harmony let and const bindings are allocated to the innermost global context;
  var and function still live on the global object.
  (Lexical bindings are not reflected on the global object at all,
  but that will probably change later using accessors, as for modules.)
- Compilation of scripts now needs a (global) context (previously only eval did).
- The global scope chain represents one logical scope, so collision tests take
  the chain into account.

Make order of addition the primary order of descriptor arrays.

The order by name is maintained as secondary order by using unused bits in the property details.

This is preliminary work towards sharing descriptors arrays.

The change allows us
- to get rid of the LastAdded bits in the map, binding it to the number of valid descriptors for the given map
- to avoid resorting by enumeration index to create the cache
- (maybe in the future, depending on performance) to get rid of the enumeration cache altogether.

Although generally the number_of_descriptors equals the NumberOfOwnDescriptors in the current version, this is preliminary work towards sharing    descriptors, where maps may have more descriptors than are valid for the map.
