NDS32: Code refactoring of relaxation.
Refactor each relaxation pattern to raise the maintainability. In origin, all patterns is analysed in nds32_elf_relax_section, so it is hard to debug and maintain. Therefore, we classify all patterns into different functions in this patch. Moreover, we adjust all optimizations into nds32_elf_relax_section to take these optimizations in turn. This can promise all relaxation being done after calling gld${EMULATION_NAME}_after_allocation.
