LoongArch: Use standard pattern name and RTX code for LSX/LASX muh instructions
Removes unnecessary UNSPECs and make the muh instructions useful with
GNU vectors or auto vectorization.
gcc/ChangeLog:
* config/loongarch/simd.md (muh): New code attribute mapping
any_extend to smul_highpart or umul_highpart.
(<su>mul<mode>3_highpart): New define_insn.
* config/loongarch/lsx.md (UNSPEC_LSX_VMUH_S): Remove.
(UNSPEC_LSX_VMUH_U): Remove.
(lsx_vmuh_s_<lsxfmt>): Remove.
(lsx_vmuh_u_<lsxfmt>): Remove.
* config/loongarch/lasx.md (UNSPEC_LASX_XVMUH_S): Remove.
(UNSPEC_LASX_XVMUH_U): Remove.
(lasx_xvmuh_s_<lasxfmt>): Remove.
(lasx_xvmuh_u_<lasxfmt>): Remove.
