PR tree-optimization/56034
* tree-loop-distribution.c (enum partition_kind): Add
PKIND_REDUCTION.
(partition_builtin_p): Adjust.
(generate_code_for_partition): Handle PKIND_REDUCTION. Assert
it is the last partition.
(rdg_flag_uses): Check SSA_NAME_IS_DEFAULT_DEF before looking
up the vertex for the definition.
(classify_partition): Classify whether a partition is a
PKIND_REDUCTION, thus has uses outside of the loop.
(ldist_gen): Inherit PKIND_REDUCTION when merging partitions.
Merge all PKIND_REDUCTION partitions into the last partition.
(tree_loop_distribution): Seed partitions from reductions as well.
* gcc.dg/torture/pr56034.c: New testcase.
