* 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.

* 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.
