[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.
