f4778b007f Reduce the memory used by frame elements from two words to one by 
encoding the values in one word and by using an indirection table for
handles.

This reduces compilation time by roughly 10% and we should be able to make the slow case equality checking of frame elements faster as well.

83f2c1968f Streamline JumpTarget::ComputeEntryFrame by removing the separate loop 
that sets the static type on elements in the entry frame.  Instead set
the static type as early as possible when computing elements.

Because the elements are shared with the reaching frames, this has the
side effect of sometimes changing the static type of reaching frame
elements.  They will be changed anyway in VirtualFrame::PrepareMergeTo
immediately after, so this is safe.

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).
