[Ada] Crash on illegal left-hand side in assignment of renamed variable
This patch fixes a crash on an assignment where the left-hand side is a
renaming of a function call that does not involve ceiling priorities.
This avoids a compiler crash in some cases, and prevents a useless
retrieval and compilation of run-time packages.

* sem_util.adb (Is_Expaned_Priority_Attribute): Check whether
call comes from a rewritten attribute before comparing name with
Get_Ceiling run-time subprogram.
gcc/testsuite/
* gnat.dg/renaming15.adb: New testcase.
