Hi!

When merging partitions together, we remove them from partitions vector,
thus don't free them at all.  Fixed thusly, bootstrapped/regtested on
x86_64-linux and i686-linux, ok for trunk?

	PR middle-end/56461
	* tree-loop-distribution.c (ldist_gen): Call partition_free after each
	partitions.ordered_remove.
