5fab2d08f2 A register allocation bugfix. 
The function that prepares a virtual frame slot for writing (in order
to preserve the copy-on-write semantics of aliased frame elements) can
allocate registers, which may spill one from the frame.  If we're
unlucky, the spilled register can be the source register for the frame
element write.  In that case, ensure we do the write from memory.

bd3019f2b6 Changed the PageIterator class so that it only returns pages existing 
at construction time.  If allocation during iteration causes a paged
space to expand, the iterator will not return the new pages.

This makes it more closely match the HeapObjectIterator behavior, and
it removes a possible source of bugs (if the allocation top was in the
last page in the space, the old iterator would stop only when it
reached the end of the space, potentially returning invalid pages from
a freshly expanded space).

b32d7d2e67 Added context information to scripts. 
Added a simple initial version of a context mirror object which just holds the user data from the context, and does not preserve handle identity.

A script object now holds a reference to the custom data from the context it was compiled in. This data is included in the debugger protocol for scripts.

Changed the serialization for the scripts command to use the mirror objects instaed of custom serialization. This included passing options from the debugger request to the serializer for including the full source of scripts in the response.
