    scan generic vector tests before lowering
    
    The g++.dg/pr94920.C testcase looks for a specific number of
    ABS_EXPRs but the vector example is prone to vector lowering so
    the following instead of scanning the optimized dump scans the
    forwprop1 dump which is before vector lowering and the point the
    transforms should have happened.
    
            * g++.dg/pr94920.C: Scan forwprop1 instead of optimized.
