Modify SizeOfFirstPage to take ool constant pool into account.

The OOL constant pool places constants in the old pointer space rather than the code space
which makes test-heap/ReleaseOverReservedPages fail. Modify SizeOfFirstPage to
increase the initial size of old-pointer space by the size of the constant pool and
decrease the code space by a corresponding amount.
