Hi,

This series adds LoongArch LASX instructions.

About test:
We use RISU test the LoongArch LASX instructions.

QEMU:
    https://github.com/loongson/qemu/tree/tcg-old-abi-support-lasx
RISU:
    https://github.com/loongson/risu/tree/loongarch-suport-lasx

Please review, Thanks.

Changes for v4:
- Rebase;
- Add avail_LASX to check.

Changes for v3:
- Add a new patch 9, rename lsx_helper.c to vec_helper.c,
  and use gen_helper_gvec_* series functions;
- Use i < oprsz / (BIT / 8) in loop;
- Some helper functions use loop;
- patch 46: use tcg_gen_qemu_ld/st_i64 for xvld/xvst{x};
- R-b.

Changes for v2:
- Expand the definition of VReg to be 256 bits.
- Use more LSX functions.
- R-b.
