ada: Reject use-clause conflicts in the run-time library
This patch fixes a bug where GNAT would fail to detect certain
errors when compiling the run-time library. In particular, if
two overloaded homographs are both directly visible, it would
pick one, rather than complaining about the ambiguity.
The problem was that some special-purpose code in Sem_Ch8 was trying
to make a user name take precedence over some run-time library
declaration that (incorrectly) appears to be visible because of
rtsfind. The solution is to disable that code while compiling
the run-time library itself.
In addition, we fix the newly-found errors in the run-time library.

* sem_ch8.adb (Find_Direct_Name): Disable the special-purpose code
when we are actually compiling the run-time library itself.

conflicts.
