    ppc: testsuite: vec-mul requires vsx runtime
    
    vec-mul is an execution test, but it only requires a powerpc_vsx_ok
    effective target, which is enough only for compile tests.  In order to
    check for runtime and execution environment support, we need to
    require vsx_hw.  Make that a condition for execution, but still
    perform a compile test if the condition is not satisfied.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.target/powerpc/vec-mul.c: Run on target vsx_hw, just
            compile otherwise.
