 swizzle is for.  Swizzle *can* however be applied to the same instruction
 as REMAP.

+In its general form, REMAP is quite expensive to set up, and on some
+implementations introduce
+latency, so should realistically be used only where it is worthwhile.
+Commonly-used patterns such as Matrix Multiply, DCT and FFT have
+helper instruction options which make REMAP easier to use.
