6d7d6d4e4e Force transition to FAST_ELEMENTS on out-of-bounds KeyedLoads. 
Proactively ensure that that objects don't get FAST_DOUBLE_ELEMENTS to reduce the number of double boxing operations when generated code calls the runtime frequently to satisfy KeyedLoad requests.

cd9bc6c3a6 Fix error handling in Date.prototype.toISOString. 
This fixes Date.prototyoe.toISOString to throw a RangeError exception
for invalid time values. It also includes a fix to removes the arbitrary
(and completely bogus) range limit on the date value during construction
of a Date object. Note that we still have bogus range limits on the year
and month values.

622d35dc0e Implement Harmony sets and maps. 
This implementation extends the internal ObjectHashTable to be able to
hold arbitrary objects (e.g. Smis, Strings, ...) as keys by applying
specialized hashing functions to primitive types. Equality of keys is
defined using the internal SameValue function.

e8bccc2cb0 Block scoped const variables. 
This implements block scoped 'const' declared variables in harmony mode. They
have a temporal dead zone semantics similar to 'let' bindings, i.e. accessing
uninitialized 'const' bindings in throws a ReferenceError.

As for 'let' bindings, the semantics of 'const' bindings in global scope is not
correctly implemented yet. Furthermore assignments to 'const's are silently
ignored. Another CL will introduce treatment of those assignments as early
errors.
