  -----------
  [SLPVectorizer] Make the insert/extractvector PHICompare a strict-weak ordering (#83571)

This was tripping off STL implementations that check for it (like libc++
with debug checking). The goal of this sort is to cluster operations on
the same values so preserve that property but sort everything else based
on the existing numbering.
