LoongArch: Improve lasx_xvpermi_q_<LASX:mode> insn pattern
For instruction xvpermi.q, unused bits in operands[3] need be set to 0 to avoid
causing undefined behavior on LA464.
gcc/ChangeLog:
* config/loongarch/lasx.md: Set the unused bits in operand[3] to 0.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/vector/lasx/lasx-xvpremi.c: Removed.
* gcc.target/loongarch/vector/lasx/lasx-xvpermi_q.c: New test.
