This CL adds a new PAYLOAD_SIZEOF specification to runtime_offsets_list.h which defines InstanceSize methods given an method name to invoke to get the header size (i.e., the size of the object portion before the payload). It uses this new specification to create appropriate InstanceSize() methods for objects written to read-only sections of snapshots, instead of needing separate size calculations for SIMARM_X64. It adds more methods to Instructions to avoid special casing for bare instructions mode. It also removes the special casing for SIMARM_X64, serializing all read-only objects in the same manner even when not in a crossword situation.
