* ira.c (allocated_reg_info_size): New static variable.
(expand_reg_info): Manage it. Call
setup_preferred_alternate_classes_for_new_pseudos.
(ira): Don't do it here. Remove local allocated_reg_info_size,
set the global before calling find_moveable_pseudos.
(find_moveable_pseudos): Call expand_reg_info rather than
resize_reg_info.
