    testsuite/92177 fix for SLP build changes
    
    We're now consistently building SLP operations with only
    scalar defs from scalars which makes the testcase no longer
    testing multiplication vectorization.  The following smuggles
    in a constant making the vector variant profitable for SLP build.
