NDS32: Set branch instruction to relaxable.
...
Relaxable fragments can be relaxed when there are alignment requirements.
Besides, insert a dummy fragment in the final to make sure that all
alignment is traversed. Finally, convert these fragments
in md_convert_frag with relax_table.

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.
