Sounds like a plan. I don't suppose anyone is working on this, righ?
I thought we could have a flag in the LLVM IR that could indicate to
the JIT compiler which parts of the code is hot and which parts is cold.
Then when we are JITing the from the compiled IR we do your suggestion
to the code.

Does that make any sence??
