* ipa-pure-const.c (struct funct_state_d): New fields
state_previously_known, looping_previously_known; remove
state_set_in_source.
(analyze_function): Use new fields.
(propagate): Avoid assumption that state_set_in_source imply
nonlooping.
* tree-ssa-loop-niter.c (finite_loop_p): New function.
* tree-ssa-loop-ivcanon.c (empty_loop_p): Use it.
* cfgloop.h (finite_loop_p): Declare.
