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).

Brief history of patch set:
v1 -> v2:
- Reduce usage of "unspec" in RTL template.
- 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)
- Combine vilvh/xvilvh insn's RTL template impl.
- Add dg-skip-if for loongarch*-*-* in vshuf test inside g++.dg/torture
  (reverted in this version)
