This patch adds basic CSKY branch instructions and symbol address series instructions. Those two kinds of instruction have relationship between each other, and it involves much work about Fixups. For now, basic instructions are enabled except for disassembler support. We would support to generate basic codegen asm firstly and delay disassembler work later.
