v3: Relax scan-assembler pattern in test case mulw_d_w.c. It's because
multiplication is Abelian and the compiler may switch the order of
operands in the future.

(mult (sign_extend:DI rj:SI) (sign_extend:DI rk:SI)) should be
"mulw.d.w", not "mul.d".
gcc/ChangeLog:
* config/loongarch/loongarch.md (mulsidi3_64bit): Use mulw.d.w
instead of mul.d.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/mulw_d_w.c: New test.
* gcc.c-torture/execute/mul-sext.c: New test.

I think there is no problem with this modification.
Thankes!
