  | Author: Richard Biener <[email protected]>

  |     Remove non-SLP vectorization factor determining
  |     
  |     The following removes the VF determining step from non-SLP stmts.
  |     For now we keep setting STMT_VINFO_VECTYPE for all stmts, there are
  |     too many places to fix, including some more complicated ones, so
  | ... 29 lines of the commit log omitted.
