    [IRA]: Fix using undefined dump file in IRA code during insn scheduling

    Part of IRA code is used for register pressure sensitive insn
    scheduling and live range shrinkage.  Numerous changes of IRA resulted
    in that this IRA code uses dump file passed by the scheduler and
    internal ira dump file (in called functions) which can be undefined or
    freed by the scheduler during compiling previous functions.  The patch
    fixes this problem.  To reproduce the error valgrind should be used
    and GCC should be compiled with valgrind annotations.  Therefor the
    patch does not contain the test case.

    gcc/ChangeLog:

            PR rtl-optimization/112610
            * ira-costs.cc: (find_costs_and_classes): Remove arg.
            Use ira_dump_file for printing.
            (print_allocno_costs, print_pseudo_costs): Ditto.
            (ira_costs): Adjust call of find_costs_and_classes.
            (ira_set_pseudo_classes): Set up and restore ira_dump_file.=
