Make JSCells have 32-bit Structure pointers
https://bugs.webkit.org/show_bug.cgi?id=123195

Reviewed by Filip Pizlo.

This patch changes JSCells such that they no longer have a full 64-bit Structure
pointer in their header. Instead they now have a 32-bit index into
a per-VM table of Structure pointers. 32-bit platforms still use normal Structure
pointers.

This change frees up an additional 32 bits of information in our object headers.
We then use this extra space to store the indexing type of the object, the JSType
of the object, some various type flags, and garbage collection data (e.g. mark bit).
Because this inline type information is now faster to read, it pays for the slowdown 
incurred by having to perform an extra indirection through the StructureIDTable.

This patch also threads a reference to the current VM through more of the C++ runtime
to offset the cost of having to look up the VM to get the actual Structure pointer.
