[patch] *hooks.[ch]: Remove unused generic hooks.

[Kazu Hirata <kazu at cs dot umass dot edu>]

Hi,

Attached is a patch to remove unused generic hooks.

IMHO, these hooks are so easy to write, so people can re-invent these
as needed.

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

	* hooks.c (hook_void_tree_int): Remove.
	(hook_void_constcharptr): Likewise.
	(hook_int_void_0): Likewise.
	* hooks.h: Remove the prototypes for the above three
	functions.
	* targhooks.c (hook_bool_machine_mode_true): Remove.
	* targhooks.h: Remove the prototype for
	hook_bool_machine_mode_true.
