ELF/BFD: Hold the number of internal static relocs in `->reloc_count'
Correct a commit e5713223cbc1 ("MIPS/BFD: For n64 hold the number of
internal relocs in `->reloc_count'") regression and change internal
relocation handling in the generic ELF BFD linker code such that, except
in the presence of R_SPARC_OLO10 relocations, a section's `reloc_count'
holds the number of internal rather than external relocations, making
the handling more consistent between GAS, which sets `->reloc_count'
with a call to `bfd_set_reloc', and LD, which sets `->reloc_count' as it
reads input sections.
The handling of dynamic relocations remains unchanged and they continue
holding the number of external relocations in `->reloc_count'; they are
also not converted to the internal form except in `elf_link_sort_relocs'
(which does not handle the general, i.e. non-n64-MIPS case of composed
relocations correctly as per the ELF gABI, though it does not seem to
matter for the targets we currently support).
The n64 MIPS backend is the only one with `int_rels_per_ext_rel' set to
non-one, and consequently the change is trivial for all the remaining
backends and targets.

* elf-bfd.h (RELOC_AGAINST_DISCARDED_SECTION): Subtract `count'
from `reloc_count' rather than decrementing it.
* elf.c (bfd_section_from_shdr): Multiply the adjustment to
`reloc_count' by `int_rels_per_ext_rel'.
* elf32-score.c (score_elf_final_link_relocate): Do not multiply
`reloc_count' by `int_rels_per_ext_rel' for last relocation
entry determination.

* elf64-mips.c (mips_elf64_get_reloc_upper_bound): Remove
prototype and function.
