partial_inplace, matching assembler output.  Set src_mask to
all ones.
(sh_elf_relocate_section): Delete misplaced comment.
For relocatable linking against section symbol, call
_bfd_relocate_contents for partial_inplace relocs and adjust
rel->r_addend for others.
<case R_SH_DIR32, R_SH_REL32>: Fetch partial_inplace addend with
bfd_get_32, not at rel->r_addend.
