[PATCH 5/8] gimple-loop-interchange.cc: use the dump API in a few places

[David Malcolm]

Doing so makes this information appear in -fopt-info, remarks,
and optimization records, rather than just in the dump_file.

gcc/ChangeLog:
	* gimple-loop-interchange.cc (tree_loop_interchange::interchange):
	Convert fprintf calls to dump_printf calls.
	(prepare_perfect_loop_nest): Likewise.
