(Apply_Discriminant_Check): Do not generate a check if the type is constrained by a current instance. (Activate_Division_Check): New procedure (Activate_Overflow_Check): New procedure (Activate_Range_Check): New procedure Call these new Activate procedures instead of setting flags directly (Apply_Array_Size_Check): Removed, no longer needed. Code clean up: remove obsolete code related to GCC 2. (Get_E_Length): Protect against bomb in case scope is standard (Selected_Range_Checks): If the node to be checked is a conversion to an unconstrained array type, and the expression is a slice, use the bounds of the slice to construct the required constraint checks. Improve NOT NULL error messages (Apply_Constraint_Check): If the context is a null-excluding access type, diagnose properly the literal null. From-SVN: r125388
