  [IRSim] Make sure that commutative intrinsics are treated as function calls without commutativity

Created to fix: https://github.com/llvm/llvm-project/issues/53537

Some intrinsics functions are considered commutative since they are performing operations like addition or multiplication. Some of these have extra parameters to provide extra information that are not part of the operation itself and are not commutative. This makes sure that if an instruction that is an intrinsic takes the non commutative path to handle this case.
