I have an experimental patch which does this and it's a todo item on our list so do something very similar. As part of the planning I think it would be beneficial to make a master document which includes a list of every optimization the compiler does and if/how it's enabled/disabled. Part of the goal is to reduce the threshold for new developers, but a key part of that will be mapping optimizations to source code.
