Log message:

contains symbols defined in the inner loop. Otherwise perform
the computation with symbols.
(no_evolution_in_loop_p): Same. Moved from here...
* tree-chrec.h (no_evolution_in_loop_p): ...there. Define it inline.
(chrec_contains_symbols_defined_in_loop): Declare.
* tree-scalar-evolution.c (nb_set_scev, nb_get_scev): New counters.
(set_scalar_evolution, get_scalar_evolution): Count the number of calls.
(chrec_contains_symbols_defined_in_loop): Defined.
(compute_scalar_evolution_after_loop, first_iteration_non_satisfying_1,
analyze_scalar_evolution_in_loop): Initialize boolean values.
(dump_chrecs_stats): Dump the get/set counters.
