* uintp.ads, uintp.adb (UI_Div_Rem): New subprogram, extending previous
implementation of UI_Div.
(UI_Div): Reimplement as a call to UI_Div_Rem.
(UI_Rem): Take advantage of the fact that UI_Div_Rem provides the
remainder, avoiding the cost of a multiplication and a subtraction.
(UI_Modular_Inverse): Take advantage of the fact that UI_Div_Rem
provides both quotient and remainder in a single computation.
(UI_Modular_Exponentiation, UI_Modular_Inverse): New modular arithmetic
functions for uint.
(UI_Modular_Inverse): Add a note that the behaviour of this subprogram
is undefined if the given n is not inversible.
