// new register choosing logic! This is gonna suck. Here goes
// The registers that are problems are the ones that have dependents in later iterations and then only
// if the schedule slot of the dependent instruction is > that of the instruction being scheduled. This
// is most esaily explained with an example
// a) add r32, r31, r31
// b) add r33, r32, 4
// c) add r34, r32, 4
// which then gets scheduled as:
// 0) add r33, r32, 4 (instruction b, iteration n + 1) ; uses r32 from previous iteration
// 1) add r32, r31, r31 (instruction a, iteration n) ; writes a new value in r32
// 2) add r34, r32, 4 (instruction c, iteration n + 1) ; error: _should_ use r32 from previous iteration
// So lets get started. Look at each instruction's output operand, and consider each dependent. If every
// dependent is in the same iteration, or in the next iteration and scheduled before the current instruction,
// then we don't need any register copying and we can just use regular register assignment logic. Otherwise,
// things start to suck. We have to first decide where to put the register copy, and that includes deciding
// whether to use odd or even pipeline, and then fix up the instruction dependents and dependencies to include
// the new copy instruction.
