[Sriraman Tallam <tmsriram at google dot com>]

Hi,

      This is a patch to move register_patch into passes.c to make it
generic to allow backends to add passes.

	* tree-pass.h (register_pass_info): New structure.
	(pass_positioning_ops): Move enum from gcc-plugin.h.
	(register_pass): New function.
	* gcc-plugin.h (plugin_pass): Delete structure.
	(pass_positioning_ops): Delete enum.
	* plugin.c (regsiter_pass): New function.
	(position_pass): New function.
	(added_pass_nodes): Delete variable.
	(prev_added_pass_nodes): Delete variable.
	(pass_list_node): Delete structure.
	* passes.c (make_pass_instance): New function.
	(next_pass_1): Change to call make_pass_instance.
	(pass_list_node): Move structure from gcc-plugin.h.
	(added_pass_nodes): Move variable from plugin.c.
	(prev_added_pass_nodes): Move variable from plugin.c.
	(position_pass): New function.
	(register_pass): New function.

Ran make check.


Thanks,
-Sriraman.
