Midgard ALU features two types of constants: embedded constants (128-bit
chunk, zero/one per schedule bundle) and inline constants (16-bit
splattered into the op, second source if present). Inline constants are
much more efficient from a space and scheduling freedom standpoint, so
it's desirable to inline when possible. Now that integer ops are well
understood and in use, we enable inlining of integers constants in
addition to floats (which have been inlined since forever).
