Read naively, this would seem to insert the mask table once for every converted ishl. That would be ungood. Does pos.func.dfg.constants.insert de-dup, and hence keep just one copy?

What does this refer to here? On the whole I'd prefer to stick with the Intel style convention, where the rightmost lane is lane zero. But note; my comment is very "drive-by"; I don't know what the lane numbering conventions in CL are.

Did you mean "shift an extra 8 bits" ?

ConstantPool does de-duplicate values but currently it is limited to a per-function boundary because of how things are compiled. I opened #1385 to talk about this some more: I think with a bit of thought we could de-duplicate across modules at least.

Ok, we can switch to Intel-style. I went back and forth on this one and I can't recall why I chose this ordering. I'll look around the file to see if there was something that made me choose this.
