d10v fixes

[Alan Modra]

Most places in bfd treat bits_per_address as a measure of the range of
addressable bytes.  d10v is a Harvard architecture processor with 256k
of insn space and 64k of data space.  bfd_arch_info_type can't
describe this properly, but 18 works better.

bfd/
	* cpu-d10v.c: Make bits_per_address 18 for all arch_info entries.
ld/testsuite/
	* ld-d10v/reloc-007.d: Don't error.
	* ld-d10v/reloc-008.d: Likewise.
	* ld-d10v/reloc-015.d: Likewise.
	* ld-d10v/reloc-016.d: Likewise.
	* ld-d10v/reloc-012.ld: Use a sane offset.
