tree-optimization/121256 - properly support SLP in vectorizable recurrence
We failed to build the correct initialization vector. For VLA
vectors and a non-uniform initialization vector this rejects
vectorization for now.
PR tree-optimization/121256
* tree-vect-loop.cc (vectorizable_recurr): Build a correct
initialization vector for SLP_TREE_LANES > 1.
* gcc.dg/vect/vect-recurr-pr121256.c: New testcase.
* gcc.dg/vect/vect-recurr-pr121256-2.c: Likewise.
