Multiple fixes: PRs 14692, 15274 and 15463
PR c++/15463
* loop-iv.c (iv_number_of_iterations): Use trunc_int_for_mode on
result of inverse.
PR rtl-optimization/15274
* loop-iv.c (determine_max_iter, shorten_into_mode,
iv_number_of_iterations): Handle constants correctly.
* rtl.h (get_mode_bounds): Declaration changed.
* stor-layout.c (get_mode_bounds): Return a constant suitable for
the target mode.
PR rtl-optimization/14692
* loop-unswitch.c (may_unswitch_on): Try folding the result.
(unswitch_single_loop): Work correctly when may_unswitch_on
returns a folded constant.
* loop-iv.c (implies_p): Handle A < B ==> A + 1 <= B.
* simplify-rtx.c (simplify_const_relational_operation): Optimize
comparisons with mode bounds.
* function.c (struct temp_slot): Add new field prev.
(free_after_compilation, init_temp_slots): Free new fields.
(cut_slot_from_list, insert_slot_to_list,
temp_slots_at_level, max_slot_level, move_slot_to_level,
make_slot_available): New functions.
(assign_stack_temp_for_type, combine_temp_slots,
find_temp_slot_from_address, preserve_temp_slots,
preserve_rtl_expr_result, free_temp_slots,
free_temps_for_rtl_expr, pop_temp_slots): Work with
the new structure of lists.
(mark_all_temps_used): Removed.
* function.h (struct function): Field x_temp_slots
replaced by x_used_temp_slots and x_avail_temp_slots.
(temp_slots): Replaced by ...
(used_temp_slots, avail_temp_slots): New.
* tree.h (mark_all_temps_used): Declaration removed.
* loop-iv.c (mark_single_set, get_biv_step_1, iv_analyze,
simplify_using_assignment): Take the expression out of
the expr_list wrapper.
* loop-iv.c (iv_number_of_iterations): Improve clasification of
infinite loops.
