re PR tree-optimization/56118 (Piecewise vector / complex initialization from constants not combined)

PR tree-optimization/56118
* tree-vectorizer.h (vect_find_last_scalar_stmt_in_slp): Declare.
* tree-vect-slp.c (vect_find_last_scalar_stmt_in_slp): Export.
* tree-vect-data-refs.c (vect_slp_analyze_node_dependences): New
function.
(vect_slp_analyze_data_ref_dependences): Instead of computing
all dependences of the region DRs just analyze the code motions
SLP vectorization will perform. Remove SLP instances that
cannot have their store/load motions applied.
(vect_analyze_data_refs): Allow DRs without a vectype
in BB vectorization.
* gcc.dg/vect/no-tree-sra-bb-slp-pr50730.c: Adjust.
