Following a previous change, the "check/assertion will fail" message is
posted on the expression rather than on the pragma keyword. This patch
makes a similar change for the "check/assertion would fail" message as
shown by the following test:

Compiling: test_assert_warning.adb

     1. procedure test_assert_warning is
     2. begin
     3.    pragma Assert (Integer'Size = 700);
                                       |
        >>> warning: assertion would fail at run-time

     4.    pragma Check (Other_Check, Integer'Size = 700);
                                                   |
        >>> warning: check would fail at run-time

     5.    pragma Assert (False);
     6.    if Integer'Size > 600 then
     7.       pragma Assert (Integer'Size = 700);
     8.       pragma Check (Other_Check, Integer'Size = 700);
     9.       null;
    10.    end if;
    11. end;
