elf32-sh.c (sh_elf_howto_tab): Make R_SH_IND12W into an ordinary
relocation (no special function), and make it non-partial_inplace.

no matter if the symbol is extern or not; set addend to -4.
Don't swap load / non-load instructions for SH4.
(sh_elf_relax_delete_bytes): In R_SH_IND12W case, check the offset
rather than if the symbol is external to determine if adjusting the
offset makes sense. Adjust the addend too if appropriate.

relocation.
