Avoid crash with GCC trunk
With GCC trunk, gdb.ada/access_to_packed_array.exp causes a GDB crash.
The problem is that ptype tries to resolve a dynamic type. However,
the inferior is not running, so there are no frames.
This patch updates dwarf2_evaluate_loc_desc::get_frame_base to handle
this situation.

* dwarf2/loc.c (dwarf2_evaluate_loc_desc::get_frame_base): Throw
if frame is null.
