Add a level of indirection to exception handler addresses.
To support deoptimization of exception handlers, the handler address in the
stack is converted to a pair of code object and an index into a separate
table of code offsets. The index part is invariant under deoptimization.
The index is packed into the handler state field so that handler size does
not change.

pages queued for freeing, so that StoreBuffer::Filter can recognize them

Some pages might have been already swept but have not been yet reached by an incremental marker (or incremental marker is not in progress) and have live bytes count set to 0.

Now every value of PropertyType should either be handled by an explicit case in

Fix size of store buffer to depend on pointer size.
This makes the store buffer size depend on the pointer size so that
store buffers can hold the same number of entries on all architectures.
The number of pages marked scan-on-scavenge should decrease on x64 and
performance of splay should drastically improve on x64.

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.

Refactoring only: Make the handling of PropertyType more explicit.
Do not rely on 'default' clauses or 'if's when analysing a PropertyType, because
this makes it hard to find the relevant places when a new type is added. Note
that the detection of "phantom property types" is left untouched, because this
might have a performance impact, especially for the GC (to be investigated).
This is a preliminary step for introducing a new kind of map transition.

Fix Harmony sets and maps to allow null as key.
This changes the internal convention for marking deleted entries in hash

This was pretty heavyweight. It was kept in just for a few corner cases
