I'm going to go a step further and mark this INVALID.
Since we already do the right thing at -Os, and there's no evidence that we're
actually generating slower code at -O2, I'm not worried about this issue. If
there's evidence that the code we're generating is slower than with a previous
compiler, post assembly code and timing information that shows that.
