[SLP]Consider (f)sub, being operand of llvm.(f)abs/icmp eq/ne 0, commutative.
If (f)sub is only operand of llvm.(f)abs or icmp eq/ne 0 (int only), we can consider it as commutative operation, just need to drop wrapping flags for ineteger
operation.
https://alive2.llvm.org/ce/z/GxvxjB for correctness of abs with dropped
flags.
