tree-optimization/97678 - fix SLP induction epilogue vectorization
This restores not tracking SLP nodes for induction initial values
in not nested context because this interferes with peeling and
epilogue vectorization.

PR tree-optimization/97678
* tree-vect-slp.c (vect_build_slp_tree_2): Do not track
the initial values of inductions when not nested.
* tree-vect-loop.c (vectorizable_induction): Look at
PHI node initial values again for SLP and not nested
inductions. Handle LOOP_VINFO_MASK_SKIP_NITERS and cost
invariants.
* gcc.dg/vect/pr97678.c: New testcase.
