Description
For vector "not", current pattern is: "XorV (Replicate -1) ". This can be improved with a single instruction "not".
For vector "andNot", current pattern is "(AndV src1 (XorV src2 (ReplicateB m1)))". This can be improved with a single instruction "bic".
These optimizations can be supported by adding match rules for Arm NEON and SVE.
