[PATCH v4 5/8] GDB/testsuite: Add coverage for `print -elements' command

[Maciej W. Rozycki]

We currently have no coverage for the `print -elements ...' command (or 
`p -elements ...' in the shortened form), so add a couple of test cases 
mimicking ones using corresponding `set print elements ...' values.

New change in v4.
