If you can keep the changes in reasonably small chunks, I think this 
would be doable. Just try to avoid the one-size-fixes-all approach of 
throwing several hundred changed methods at a single point in time.

I doubt that looking at the generated code will help much in general 
unless you can find a way to run gcc over these methods and have it show 
us directly the things it doesn't like. As a matter of fact, I think a 
non-inlined VM would be a much better starting point since it will only 
report each problem once and not every time it trips over an inlined 
variant.
