[PATCH] Make add_phi_node_to_bb static

[Richard Biener <rguenther@suse.de>]

The only exported PHI allocation already adds the PHI node to a block.

Bootstrapped on x86_64-unknown-linux-gnu, pushed.

	* tree-phinodes.h (add_phi_node_to_bb): Remove.
	* tree-phinodes.cc  (add_phi_node_to_bb): Make static.
