    RA: Constrain class of pic offset table pseudo to general regs

    On some targets an integer pseudo can be assigned to a FP reg.  For
    pic offset table pseudo it means we will reload the pseudo in this
    case and, as a consequence, memory containing the pseudo might be
    recognized as wrong one.  The patch fix this problem.

    gcc/ChangeLog:

            * ira-costs.cc: (find_costs_and_classes): Constrain classes of =

            offset table pseudo to a general reg subset.
