-stack-list-arguments will crash when stopped in an Ada procedure that
has an argument with a certain name ("_objectO" -- which can only be
generated by the compiler). The bug occurs because lookup_symbol will
fail in this case.
This patch changes -stack-list-arguments to mirror what is done with
arguments elsewhere. (As an aside, I don't understand why this lookup
is even needed, but I assume it is some stabs thing?)
In the longer term I think it would be good to share this code between
MI and the CLI. However, due to the upcoming release, I preferred a
more local fix.
