IIUC, intrinsics are defined with variable no of srcs and dsts and I'm not sure if it's possible for any legalization query to specify actions(custom) based on intrinsic id which would imply different types for different operands. Also, this patch was written a long time and at that time it wasn't possible to specify intrinsic ids + operands for legalization rules. Also, I'm not sure if it's' possible now.
