I can emulate **control flow** very closely with user mode thread switching
APIs like make_context, jump_context. Memory behavior not so much.
Library emulation
=================
Let's build a fiber abstraction out of make_context, jump_context.
i1 fiber_fork(i8* %mem) - clones this function into a fiber
returns 0 - in a fiber
returns 1 - in a thread...

I think I got it. Original model (with coro.fork and two-way coro.suspend)
will work with a tiny tweak.
In the original model, I was replacing coro.suspend with br %return in original
function. The problem was coming from potential phi-nodes introduces into
return block during optimizations.
Let's make sure that there is only entry into the return block.
In the original model, ReturnBB had
