[PATCH v2] Minor cleanups in ada-nested.exp

[PATCH v2] Minor cleanups in ada-nested.exp

[Tom Tromey]

This changes ada-nested.exp to fix a test name (the test expects three
variables but is named "two"), and to iterate over all the variables
that are found.  It also adds a workaround to a problem Tom de Vries
found with an older version of GNAT -- it emits a duplicate "x".

I applied the patch and get a DUPLICATE message:
...
Running /data/vries/gdb/src/gdb/testsuite/gdb.dap/ada-nested.exp ...
DUPLICATE: gdb.dap/ada-nested.exp: check value of x

		=== gdb Summary ===

# of expected passes		17
# of duplicate test names	1
...

Otherwise LGTM.

Thanks,
- Tom

Oops, sorry about that.

I've fixed that & now I'm going to push this.
Will backport as well.
