* tree-inline.c (estimate_num_insns): Refactor builtin complexity
lookup code into....
* builtins.c (is_simple_builtin, is_inexpensive_builtin): ...these
new functions.
* tree.h (is_simple_builtin, is_inexpensive_builtin): Declare.
* cfgloopanal.c (target_clobbered_regs): Define.
(init_set_costs): Initialize target_clobbered_regs.
(estimate_reg_pressure_cost): Add call_p argument. When true,
adjust the number of available registers to exclude the
call-clobbered registers.
* cfgloop.h (target_clobbered_regs): Declare.
(estimate_reg_pressure_cost): Adjust declaration.
* tree-ssa-loop-ivopts.c (struct ivopts_data): Add body_includes_call.
(ivopts_global_cost_for_size): Pass it to estimate_reg_pressure_cost.
(determine_set_costs): Dump target_clobbered_regs.
(loop_body_includes_call): New function.
(tree_ssa_iv_optimize_loop): Use it to initialize new field.
* loop-invariant.c (gain_for_invariant): Adjust arguments to pass
call_p flag through.
(best_gain_for_invariant): Likewise.
(find_invariants_to_move): Likewise.
(move_single_loop_invariants): Likewise, using already-computed
has_call field.
