here's an odd-looking little fellow:
```llvm
define i1 @f(i1 %V) {
%C1 = fcmp false double 0.000000e+00, 0.000000e+00
%brmerge = select i1 %C1, i1 true, i1 %V

I wonder if it would be in scope for the `xvec` accessor to have a method that can be used to convert two bounds coordinates to `shapely` geometry columns?
I'd imagine something like this:
