	* regcache.c (read_pc, write_pc): Remove.

	* infrun.c (displaced_step_fixup): Use regcache_read_pc instead
	of read_pc.
	(handle_inferior_event): Use regcache_read_pc instead of read_pc
	when determining value of stop_pc.  Replace subsequent uses of
	read_pc by inspecting already-retrieved stop_pc value.
	(keep_going): Use regcache_read_pc instead of read_pc.

	* breakpoint.c (watchpoint_check): Use current frame architecture
	and PC instead of current_gdbarch and read_pc ().
	* tracepoint.c (set_traceframe_context): Replace PC argument
	with FRAME argument.
	(trace_start_command, finish_tfind_command): Update calls.
	(finish_tfind_command): Compare frame IDs to identify transitions
	between frames.
	(trace_find_pc_command): Use regcache_read_pc instead of read_pc.
	* rs6000-nat.c (exec_one_dummy_insn): Pass in regcache instead
	of gdbarch.  Use regcache_read_pc and regcache_write_pc instead
	of read_pc and write_pc.
	(store_register): Make regcache argument non-const.  Update call
	to exec_one_dummy_insn.
