  Log Message:
  -----------
  [SLP]Pre-cache the last instruction for all entries before vectorization

Need to pre-cache last instruction to avoid unexpected changes in the
last instruction detection during the vectorization, caused by adding
the new vector instructions, which add new uses and may affect the
analysis.
