That is entirely possible.  However, LLVM evolution is driven by 
experience.  This means we prefer to implement something the 
straight-forward way using existing features if we can, instead of adding 
a bunch of stuff to LLVM all of the time.  This shows us exactly what the 
problems are, and allows us to understand what a good solution would look 
like.

If you propose a simple extension "in the spirit of LLVM" and demonstrate 
how it makes the produced code better in some way, there is a good chance 
that we'll accept it.  However, if the extension is language or target 
specific, is not "low level", is complex, etc, we probably won't.
