This CL adds the shared barrier to the RecordWrite builtin which is
used in generated code for builtins, interpreted and optimized code.

The out-of-line part of the barrier now checks whether either the
POINTERS_TO_HERE_ARE_INTERESTING or the IN_SHARED_HEAP bit is set in
the value object's page flags.

Outside of marking the RecordWrite builtin now needs to check whether
to insert into the generational or shared remembered set. Inserting
into the shared remembered set will always call into C++ code.

During marking the RecordWrite builtin now also needs to check whether
this store created an old-to-shared pointer.
