tree-optimization/116566 - single lane SLP for VLA inductions

The following adds SLP support for vectorizing single-lane inductions
with variable length vectors.

PR tree-optimization/116566
* tree-vect-loop.cc (vectorizable_induction): Handle single-lane
SLP for VLA vectors.

* gcc.dg/tree-ssa/reassoc-46.c: When using partial vectors
the dump-scan doesn't look for the required .COND_ADD so
skip for partial vectors.
