Summary

This is my first attempt to implement mul instruction legalization for wider-than-legal types.

It reduces one full precision mul to 8 half precision muls using basic school approach. It is probably only useful up to i512 types.

chfast retitled this revision from to Multiplication for wider-than-legal types.
