Log message:
* tree-chrec.c (chrec_fold_automatically_generated_operands,
chrec_merge):
Use chrec_dont_know instead of a call to chrec_contains_undetermined.
(tree_fold_factorial, tree_fold_binomial, chrec_evaluate): Resurrect.
(chrec_apply): Reinsert the cases that were removed.
(chrec_convert): Remove the check for NULL_TREE inserted two days ago.
* tree-scalar-evolution.c (follow_ssa_edge_in_rhs): As a sequel of
removing the tree_fold_* functions, the analyzed trees can contain
NON_LVALUE_EXPR nodes. Use STRIP_TYPE_NOPS for avoiding these nodes.
(number_of_iterations_in_loop): Add the missing open parenthesis in
the debugging dumps.
(initialize_scalar_evolutions_analyzer): Use an INTERVAL_CHREC for
constructing the chrec_dont_know node. This fixes some strange
problems that arise when chrec_dont_know is an INTEGER_CST.
* tree.def (INTERVAL_CHREC): Resurrect.
