* ia64-tdep.c (ia64_libunwind_frame_this_id): Adapt uses of

libunwind_frame_prev_register to use a gdb_byte buffer and
	extract_unsigned_integer.
	(ia64_libunwind_sigtramp_frame_prev_register): Likewise.

	* libunwind-frame.c (libunwind_frame_prev_register): Change type
	of last argument to `gdb_byte *'
	* libunwind-frame.h: Adjust declaration.
