Add support for %hi8, %hi16 and %lo16 being used when relocation are necessary.
* config/tc-rl78.c (rl78_op): Issue an error message if a 16-bit
relocation is used on an 8-bit operand or vice versa.
(tc_gen_reloc): Use the RL78_16U relocation for RL78_CODE.
(md_apply_fix): Add support for RL78_HI8, RL78_HI16 and RL78_LO16.
