[PATCH 2/2] extend scope of testing in gdb.ada/arrayptr

[Joel Brobecker]

We add testing of taking a slice of an array access.  And we also
introduce the same amount of testing, but with an access to a
constrained array.

Without the previous change, we get 2 FAILs:
    FAIL: gdb.ada/arrayptr.exp: print arr_ptr (2)
    FAIL: gdb.ada/arrayptr.exp: print arr_ptr (3..4)

gdb/testsuite/ChangeLog:

        * gdb.ada/arrayptr/foo.adb: Add access to constrained array.
        * gdb.ada/arrayptr.exp: Add new tests.

Tested on x86_64-linux.  Will commit in a couple of days.
