MIPS: Sync elf.h from binutils
Add new definitions for the MIPS target, specifically: relocation types, machine flags, section type names, and object attribute tags and values. On MIPS64, up to three relocations may be specified within r_info, by the r_type, r_type2, and r_type3 fields, so add new macros to get the respective reloc types for MIPS64.
