[PATCH 04/14] add make_unqualified_type

[Tom Tromey <tromey@redhat.com>]

There's seemingly no function to get the unqualified variant of a
type, so this patch adds one.  This new function will be used in the
final patch.

2014-05-16  Tom Tromey  <tromey@redhat.com>

	* gdbtypes.h (make_unqualified_type): Declare.
	* gdbtypes.c (make_unqualified_type): New function.
