Don't use INTDEF/INTUSE in unwind-dw2-fde.c (bug 14132)

["Joseph S. Myers" <joseph at codesourcery dot com>]

Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this
patch replaces its use in unwind-dw2-fde.c with hidden_def and
hidden_proto.

Tested for x86.  This patch does result in code generation differences
(for some reason GCC decides to partition __register_frame_info_bases
after the patch).

	[BZ #14132]
	* sysdeps/generic/unwind-dw2-fde.c
	(__register_frame_info_bases_internal): Do not declare.
	(__register_frame_info_table_bases_internal): Likewise.
	(__deregister_frame_info_bases_internal): Likewise.
	(__register_frame_info_bases): Declare and use hidden_proto before
	definition.  Use hidden_def instead of INTDEF.
	(__register_frame_info_table_bases): Likewise.
	(__deregister_frame_info_bases): Likewise.
	(__register_frame_info): Do not use INTUSE.
	(__register_frame): Likewise.
	(__register_frame_info_table): Likewise.
	(__register_frame_table): Likewise.
	(__deregister_frame_info): Likewise.
	(__deregister_frame): Likewise.
