This results in the lane number being encoded verbatim in the VSRC1 instruction
field, which I don't think is correct?

I tried adding 0x80 to make it an inline literal, but Sanctuary still locks up.

Another potential gotcha I noticed in the ISA documentation is that the
V_READ/WRITELANE instructions don't respect the EXEC mask.
