Hi,
We tested some basic system commands using LoongArch clfs system.
and supported 'make check-tcg'. Of course. this series only support linux-user
emulation.
Changes for v4:
* Update README，add LoongArch linux-user emulation Introduction.
* Add 'make check-tcg' support(patch 20).
* Add binfmt config(patch 21).
* Fix bugs when running loongarch basic commands.
Changes for v3:
* Split trans.inc.c.
* Remove csr registers.
* Delete patchs 2, 4, 5.
* Follow Richard's code review comments [1].
* Follow Richard's riscv patches [2].

Changes for v2:
* Patch 1, remove unnecessary introduction;
* Patch 3, follow the ARM/AVR pattern to add new CPU features;
* Patch 6, remove decode_lsx();
* Patches 7-18, delete opcode definition, modify translation function;
* Patches 20-22, split V1 patch20 to V2 patch20-22.
V3:
