[Ada] Improve support for tuning branch probability heuristics

This adds a new GNAT.Branch_Prediction package to make it possible to
tune the branch probability heuristics more finely.  This package
contains the equivalent of __builtin_expect in C/C++ plus a couple of
specializations.

The following program gives a summary of the usage:

package Q is

  I : Integer;
  pragma Volatile (I);

end Q;

with GNAT.Branch_Prediction; use GNAT.Branch_Prediction;
with Text_IO; use Text_IO;
with Q; use Q;

procedure P is
begin
  if Unlikely (I = 0) then
    Put_Line ("Zero was passed");
    return;
  end if;

  if Likely (I > 0) then
    Put_Line ("A positive number was passed");
  else
    Put_Line ("A negative number was passed");
  end if;

  if Expect ((I rem 2) = 0, False) then
    Put_Line ("An even number was passed");
  else
    Put_Line ("An odd number was passed");
  end if;
end;

+--  This package provides routines giving hints to the branch predictor of the

+--  branch probability heuristics are used (which is the default), but they are
+--  overridden when profile feedback-directed optimization is used instead.
+
+--  The canonical pattern is to use them as the condition of an If statement:
+--
+--     if Likely (X > 0) then
+--        Do_Something;
+--     end if;
+--
+--  when it is not obvious that one outcome of the condition is more likely
+--  than the other, or else to reverse the prediction made by the heuristics
+--  in very peculiar cases. In the other cases, it is better not to use them,
+--  because predicting how programs actually perform is notoriously hard.
