[patch] tree-ssa-loop-niter.c: Make some functions static.

[Kazu Hirata]

Hi,

Attached is a patch to make upper_bound_in_type and
lower_bound_in_type static as they are used only from
tree-ssa-loop-niter.c.

Bootstrapped on i686-pc-linux-gnu.  OK to apply?

	* tree-ssa-loop-niter.c (upper_bound_in_type,
	lower_bound_in_type): Make them static.
	* tree.h: Remove the corresponding prototypes.
