S12Z: Emit RELOC_S12Z_OPR instead of RELOC_EXT24 where appropriate.
When assembling instructions which involve OPR references, emit RELOC_S12Z_OPR instead of RELOC_EXT24. bfd/ * bfd-in2.h [BFD_RELOC_S12Z_OPR]: New reloc. * libbfd.h: regen. * elf32-s12z.c (eld_s12z_howto_table): R_S12Z_OPR takes non zero source field. (md_apply_fix): Apply final fix to BFD_RELOC_S12Z_OPR. * reloc.c[BFD_RELOC_S12Z_OPR]: New reloc. gas/ * config/tc-s12z.c (emit_opr): Emit BFD_RELOC_S12Z_OPR instead of BFD_RELOC_24. * testsuite/gas/s12z/opr-indirect-expr.d: Expect R_S12Z_OPR instead of R_S12Z_EXT24.
