This change makes the scatter/gather syntax more consistent with the syntax of all the other memory operations in the Vector dialect (order of types, use of [] for index, etc.). This will make the MLIR code easier to read. In addition, the pass_thru parameter of the gather has been made mandatory (there is very little benefit in using the implicit "undefined" values).
