instruction to execute. This can be used for transformations (like two-address
conversion) to remat an instruction instead of generating a "move"
instruction. The idea is to decrease the live ranges and register pressure and
all that jazz.

that it's safe to remat an instruction.

Factor the numbering computation into a separate method, and add the slightest attempt at some renumbering logic, which is currently unused.

v2f64 = vzext_load f32mem
