This is an update of:
https://gcc.gnu.org/pipermail/gcc-patches/2023-August/628303.html
Changes since last version of patch set:
- "dg-skip-if"-related Changes of the g++.dg/torture/vshuf* testcases are
reverted.
(Replaced by __builtin_shuffle fix)
- Add fix of __builtin_shuffle() for Loongson SX/ASX (Implemeted by adding
vand/xvand insn in front of shuffle operation). There's no significant
performance
impact in current state.
- Rebased on the top of Yang Yujie's latest target configuration interface
patch set
(https://gcc.gnu.org/pipermail/gcc-patches/2023-August/628772.html).

- Append Support of ADDR_REG_REG in LSX and LASX.
- Constraint docs are appended in gcc/doc/md.texi and ccomment block.
- Codes related to vecarg are removed.
- Testsuite of LSX and LASX is added in v2. (Because of the size limitation of
mail list, these patches are not shown)
- Adjust the loongarch_expand_vector_init() function to reduce instruction
output amount.
- Some minor implementation changes of RTL templates.
v2 -> v3:
- Revert vabsd/xvabsd RTL templates to unspec impl.
- Resolve warning in gcc/config/loongarch/loongarch.cc when bootstrapping
with BOOT_CFLAGS="-O2 -ftree-vectorize -fno-vect-cost-model -mlasx".
- Remove redundant definitions in lasxintrin.h.
- Refine commit info.
v3 -> v4:
- Code simplification.
- Testsuite patches are splited from this patch set again and will be
submitted independently in the future.
v4 -> v5:
- Regression test fix (pr54346.c)
