[InstCombine] Pull unary shuffles through fneg/fabs (llvm#144933)
This canonicalizes fneg/fabs (shuffle X, poison, mask) -> shuffle (fneg/fabs X), posion, mask This undoes part of b331a7e and a8f13db, but keeps the binary shuffle case i.e. shuffle fneg, fneg, mask. By pulling out the shuffle we bring it inline with the same canonicalisation we perform on binary ops and intrinsics, which the original commit acknowledges it goes in the opposite direction. However nowadays VectorCombine is more powerful and can do more optimisations when the shuffle is pulled out, so I think we should revisit this. In particular we get more shuffles folded and can perform scalarization.
