Side note: I'd also like the commit that introduces this to talk very
explicitly about the particular case that it is used doe and that it
fixes. No "this can happen". A "this happened, here's the _actual_
wrong code generation, and look how this new ctrl_dep() macro fixes
it".
When it's this subtle, I don't want theoretical arguments. I want
actual outstanding and real bugs.
Because I get the feeling that there were very few actual realistic
examples of this, only made-up theoretical cases that wouldn't ever
really be found in real code.
