<pre>We don't currently do a very good job of testing the various costs of
instructions based on the specific schedule model used (generic, atom,
sandybridge, haswell, silvermont, jaguar).
To help improve this it would be useful to have an option to to output assembly
comments that indicate latency/throughput etc. of each instruction. We should
then create a set of test files that cover a decent range of instructions.</pre>
