Hi,

This series adds LoongArch LSX instructions.

About test:
V2 we use RISU test the LoongArch LSX instructions.

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

Build test:
make docker-test-build@fedora-i386-cross

V5:
  - R-b and rebase;
  - vld/vst{x} Memop = MO_128 | MO_TE.

V4:
  - R-b and rebase;
  - Migrate the upper half lsx regs;
  - Remove tcg_gen_mulus2_*;
  - Vsetallnez use !do_match2;
  - Use tcg_gen_concat_i64_i128/tcg_gen_extr_i128_i64 to replace 
    TCGV128_LOW(val)/TCGV128_High(val);

V3:
  - R-b;
  - Add unsigned data type in vreg;
  - Add ctx->vl;
  - Use tcg_constant_vec_matching instead of dupi;
  - Use __typeof(Vd->E(0)) instead of the output type;
  - Tcg integer expansion;
  - Use tcg_gen_qemu_ld/st_i128 to implement vld/vst;
  - Fix some typos;
  - Optimize code based on Richard's comments.

V2:
  - Use gvec;
  - Fix instructions bugs;
  - Add set_fpr()/get_fpr() replace to cpu_fpr.
