3fc277f6 - [SLPVectorizer] Make the insert/extractvector PHICompare a strict-weak ordering (#83571)

[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.
