	   * corelow.c: Include "arch-utils.h", "regset.h" and
	   "gdb_assert.h".
	   (core_gdbarch): New variable.
	   (sniff_core_bfd): Don't sniff if we have support for register sets
	   in CORE_GDBARCH.
	   (core_close): Reset CORE_GDBARCH.
	   (core_open): Initialize CORE_GDBARCH.
	   (get_core_register_section): Use register sets if they are
	   supported by CORE_GDBARCH.
	   (get_core_registers): Don't print error message if we have support
	   for register sets in CORE_GDBARCH.

I checked this in now.  If your favourite target suddenly starts doing
weird things with its core files, please tell me!
