This patch series allows qemu to utilize LSX instructions on LoongArch
machines to execute TCG vector ops.

Passed tcg tests with x86_64 and aarch64 cross compilers.

Changes since v2:

- Add vece argument to tcg_target_const_match() for const args of vector ops
- Use custom constraint for cmp_vec/add_vec/sub_vec for better const arg handling
- Implement 128-bit load & store using vldx/vstx

Changes since v1:

- Optimize dupi_vec/st_vec/ld_vec/cmp_vec/add_vec/sub_vec generation
- Lower not_vec/shi_vec/roti_vec/rotv_vec
