[PATCH 8/9] Use value_at_non_lval in get_call_return_value

[Tom Tromey <tromey@adacore.com>]

get_call_return_value can handle RETURN_VALUE_STRUCT_CONVENTION,
because the call is completely managed by gdb.  However, it does not
handle variably-sized types correctly.  The simplest way to fix this
is to use value_at_non_lval, which does type resolution.
