[Ada] SPARK pointer support extended to local borrowers and observers
SPARK rules allow local borrowers and observers to be declared. During
their lifetime, the access to the borrowed/observed object is
restricted.
There is no impact on compilation.

* sem_spark.adb: Add support for locally borrowing and observing
a path.
(Get_Root_Object): Add parameter Through_Traversal to denote
when we are interesting in getting to the traversed parameter.
(Is_Prefix_Or_Almost): New function to support detection of
illegal access to borrowed or observed paths.
(Check_Pragma): Add analysis of assertion pragmas.
