commit r14-2187-g2b31dc28c752146d2917a1702d20eac12701d034

    [Committed] Add -mmove-max=128 -mstore-max=128 to pieces-memcmp-2.c
    
    Adding -mmove-max=128 and -mstore-max=128 to the dg-options of the
    recently added gcc.target/i386/pieces-memcmp-2.c avoids changing the
    intent of this testcase when adding -march=cascadelake to RUNTESTFLAGS.
    Committed as obvious.

    gcc/testsuite/ChangeLog
            * gcc.target/i386/pieces-memcmp-2.c: Specify that 128-bit
            comparisons are desired, to see if 256-bit instructions are
            generated inappropriately (fixes test on -march=cascadelake).
