* rl78-tdep.c (rl78_register_reggroup_p): Include SP in the
`save' and `restore' register groups. Don't include SPL
or SPH in these groups.
(rl78_dwarf_reg_to_regnum): Adjust mapping for
RL78_PC_REGNUM. Add mappings for RL78_PSW_REGNUM,
RL78_ES_REGNUM, and RL78_CS_REGNUM.
(rl78_gdbarch_init): Set `dwarf2_addr_size' to 4. Invoke
dwarf2_append_unwinders().
