    c++: further concept_check_p clean-up
    
    Patrick noticed a few more concept_check_p checks that can be removed
    now.
    
    gcc/cp/ChangeLog:
    
            * constexpr.cc (cxx_eval_call_expression): Remove concept_check_p 
check.
            (cxx_eval_outermost_constant_expr): Likewise.
            * cp-gimplify.cc (cp_genericize_r) <case CALL_EXPR>: Likewise.
            * except.cc (check_noexcept_r): Likewise.
