    predcom: Fix up component::component [PR105056]
    
    The recent change didn't initialize comp_step while previously we used
    XCNEW to allocate it.
    
    I think RS_ANY is better than RS_INTERNAL (== 0) as the default.

            * tree-predcom.cc (component::component): Initialize also comp_step.
