I should note the non-constant case is already handled:
```
int unopt(int n, int c) {
if (n / c)
return n / c;
else
return 0;
}
```
It is just the constant case that has issues.

If it helps, I have reduced the patches to just the two that strictly necessary
for stage 1 build (I can't get rid of those, sorry, that would be asking for
the impossible), which are:

I don't think builds with completely unchanged source are going to work, as the
compiler won't even reach this point then (at very least several of them are
necessary for stage 1 to build at all)

Current patch is incomplete as it fails to scalarize.
It seems I need to remember how to register the new
intrinsic subprograms in trans-intrinsics.cc.

So far that's the only fallout I've seen on the embedded targets.
The qemu emulated natives aren't running as I've got some kind of network
problem here and the workers are going offline after a few hours
