Log message:
PR tree-optimization/23942
* Makefile.in (SCEV_H): Depends on PARAMS_H.
* tree-scalar-evolution.c: Include params.h.
(t_bool): New enum.
(follow_ssa_edge, follow_ssa_edge_in_rhs,
follow_ssa_edge_in_condition_phi_branch,
follow_ssa_edge_in_condition_phi, follow_ssa_edge_inner_loop_phi):
Change return type to t_bool. Use a parameter to limit the size of
trees that are walked before stopping
(analyze_evolution_in_loop): Initialize the limit to 0.
(follow_ssa_edge): Give up by returning t_dont_know if the limit
exceeds PARAM_SCEV_MAX_EXPR_SIZE.
