rl78: relaxation fixes
Various fixes to linker relaxation. In general, we need to support
relaxing every branch, even if we don't relax it in the assembler,
so we can optionally defer relaxation to the linker.
* elf32-rl78.c (rl78_offset_for_reloc): Add more relocs.
(rl78_elf_relax_section): Add bc/bz/bnc/bnz/bh/bnh. Fix reloc
choices.
* config/rl78-parse.y: Make all branches relaxable via
rl78_linkrelax_branch().
* config/tc-rl78.c (rl78_linkrelax_branch): Mark all relaxable
branches with relocs.
(options): Add OPTION_NORELAX.
(md_longopts): Add -mnorelax.
(md_parse_option): Support OPTION_NORELAX.
(op_type_T): Add bh, sk, call, and br.
(rl78_opcode_type): Likewise.
(rl78_relax_frag): Fix not-relaxing logic. Add sk.
(md_convert_frag): Fix relocation handling.
(tc_gen_reloc): Strip relax relocs when not linker relaxing.
(md_apply_fix): Defer overflow handling for anything that needs a
PLT, to the linker.
* config/tc-rl78.h (TC_FORCE_RELOCATION): Force all relocations to
the linker when linker relaxing.
* doc/c-rl78.texi (norelax): Add.
