This modifies my previous patch to push the strided load formation to isel. This gives us opportunity to fold the splat into a .vx operation first. Using a scalar register and a .vx operation reduces vector register pressure which can be important for larger LMULs. If we can't fold the splat into a .vx operation, then it can make sense to use a strided load to free up the vector arithmetic ALU to do actual arithmetic rather than tying it up with vmv.v.x.
