tree-pass.h (tree_lowering_passes): Remove.

2012-04-10  Richard Guenther  <rguenther@suse.de>

	* tree-pass.h (tree_lowering_passes): Remove.
	* tree-optimize.c (tree_lowering_passes): Remove.
	* cgraph.c (cgraph_add_new_function): Inline relevant parts
	of tree_lowering_passes, avoid redundant call of early local
	passes.
	* cgraphunit.c (cgraph_lower_function): Fold into ...
	(cgraph_analyze_function): ... its single caller.  Inline
	relevant parts of tree_lowering_passes.
