[PATCH 1/3] LoongArch: testsuite: Fix pr112325.c and pr117888-1.c.

[Lulu Cheng]

By default, vectorization is not enabled on LoongArch,
resulting in the failure of these two test cases.

gcc/testsuite/ChangeLog:

        * gcc.dg/vect/pr112325.c: Add the vector compilation
        option '-mlsx' for LoongArch.
        * gcc.dg/vect/pr117888-1.c: Likewise.
