        * sem_intr.adb (Check_Shift): Use RM_Size instead of Esize, when
        checking that the 'Size is correct. If the type is "mod 2**12",
        for example, it's illegal, but Esize is the 'Object_Size, which
        will be something like 16 or 32, so the error ('Size = 12) was
        not detected.
        * gnat_rm.texi: Improve documentation of shift
        and rotate intrinsics.

        * prj.adb (For_Every_Project_Imported): Fix
        implementation to make sure we return each project only once
        for aggragte libraries. It is fine to return a project twice for
        aggregate projects, this was the case as a Project_Id is different
        in each project tree. The new implementation use a table based on
        the project name to ensure proper detection of duplicate project
        in aggregate library. A new context is then created to continue
        retrurning duplicate project for aggregate libraries.
