This makes it so that the Ada compiler emits named pointer types in the debug
info (DW_TAG_typedef in DWARF) for pointer types declared in the sources.
Tested on i586-suse-linux, applied on the mainline.

* gcc-interface/utils.c (gnat_pushdecl): If this is a non-artificial
declaration of a pointer type, then set DECL_ORIGINAL_TYPE to a
distinct copy.
