lto: Fix reversed sorting of node order.

Sorting by node order in lto partitioning is incorrectly reversed.
For default balanced partitioning this caused all noreorder symbols
to be partitioned into a single partition where they were sorted again,
but correctly.

gcc/lto/ChangeLog:

	* lto-partition.cc (cmp_partitions_order): Reverse sort.
	(node_cmp): Reverse sort.
