  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.
Tested on x86_64-pc-linux-gnu.  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).
