[RFC PATCH 00/43] Add LoongArch LSX instructions

[Song Gao]

Hi, Merry Christmas!

This series adds LoongArch LSX instructions, Since the LoongArch
Vol2 is not open, So we use 'RFC' title. 
 
About Test:
The new-abi gcc which support LSX is also not open, We use the old-abi gcc [1] 
build 
test code[2](tests/tcg/loongarch/vec/test_XXX*.c).

[1]:http://ftp.loongnix.cn/toolchain/gcc/release/loongarch/gcc8/loongson-gnu-toolchain-8.3-x86_64-loongarch64-linux-gnu-rc1.1.tar.xz
 
[2]:https://github.com/loongson/qemu/commit/a4f03d68c0c60fcc5bf62114fd1f7a6a7cdf1070

e.g
   build:
   loongarch64-linux-gnu-gcc -mlsx tests/tcg/loongarch64/vec/test_bit.c -o 
test_bit
   run:
   ./build/qemu-loongarch64  test_bit   (qemu branch [2]: 
tcg-old-abi-support-lsx)

Thanks.
