Very interesting, thanks for working on this!

I will do a detailed review soon. At a first glance it looks like this patch could be split up into a part affecting MC and one affecting the AsmPrinters? That would ease review and improve chances that some parts get accepted sooner.

There is always the chance for less instruction caches misses if the cold code is out of the way. On top of this it should improve application startup time as there is a chance that the cold code will never be loaded from disk.
