[Ada] Illegal selection of first object in a task type's body not detected
The compiler was improperly allowing selection of an object declared
within a task body when the prefix was of the task type, specifically in
the case where the object was the very first declared in the body
(selections of later body declarations were being flagged). The flag
Is_Private_Op was only set at the point of the first "private"
declaration of the type in cases where the first declaration's name
didn't match the selector.

gcc/ada/
* sem_ch4.adb (Analyze_Selected_Component): In the case where
the prefix is of a concurrent type, and the selected entity
matching the selector is the first private declaration of the
type (such as the first local variable in a task's body), set
Is_Private_Op.
gcc/testsuite/
* gnat.dg/task5.adb: New testcase.
