Refactor gold to enable support for MIPS-64 relocation format.
For MIPS-64, the r_info field in the relocation format is replaced by several individual fields, including r_sym and r_type. To enable support for this format, I've refactored target-independent code to remove almost all uses of the r_info field. (I've left alone a couple of routines used only for incremental linking, which I can update if/when the MIPS target adds support for incremental linking.) For routines that are already templated on a Classify_reloc class (namely, gc_process_relocs, relocate_section, and relocate_relocs), I've extended the Classify_reloc interface to include sh_type (which no longer needs to be a separate template parameter) as well as get_r_sym() and get_r_type() methods for extracting the r_sym and r_type fields. For scan_relocatable_relocs, I've extended the Default_scan_relocatable_relocs class by converting it to a class template with Classify_reloc as a template parameter. For the remaining routines that need to access r_sym, I've added a virtual Target::get_r_sym() method with an override for the MIPS target. In elfcpp, I've added Mips64_rel, etc., accessor classes and corresponding internal data structures. The MIPS target uses these new classes within its own Mips_classify_reloc class. The Mips64_ accessor classes also expose the r_ssym, r_type2, and r_type3 fields from the relocation. These changes should be functionally the same for all but the MIPS target. elfcpp/ * elfcpp.h (Mips64_rel, Mips64_rel_write): New classes. (Mips64_rela, Mips64_rela_write): New classes. * elfcpp_internal.h (Mips64_rel_data, Mips64_rela_data): New structs. gold/ * gc.h (get_embedded_addend_size): Remove sh_type parameter.

[GOLD] Relocate::relocate() params
Some linker code editing needs to change multiple insns. In some cases multiple relocations are involved and it is not sufficient to make the changes independently as relocations are processed, because doing so might lead to a partial edit. So in order to safely edit we need all the relocations available in relocate(). Also, to emit edited relocs corresponding to the edited code sequence we need some way to pass information from relocate() to relocate_relocs(), particularly if the edit depends on insns. We can't modify input relocs in relocate() as they are mmapped PROT_READ, nor it is particularly clean to write relocs to the output at that stage. So add a Relocatable_relocs* field to relinfo to mark edited relocs. Given that relocate is passed the raw reloc pointer, it makes sense to remove the rel/rela parameter and r_type too. However, that means the mips relocate() needs to know whether SHT_REL or SHT_RELA relocs are being processed. So add a rel_type for mips, which also has the benefit of removing relocate() overloading there. This patch adds the infrastructure without making use of it. Note that relinfo->rr will be NULL if not outputting relocations. * object.h (struct Relocate_info): Add "rr". * reloc.h (Relocatable_relocs::set_strategy): New accessor. * reloc.cc (Sized_relobj_file::do_relocate_sections): Init relinfo.rr for relocate_section and relocate_relocs. * powerpc.cc (relocate): Add rel_type and preloc parameters.
