I'm not sure how experimental this PR is supposed to be, but I am unable to compile a simple test program with an If statement:

``` fortran
program r
  integer :: n = 1
  if (n > 0) n = 2
end program r
```

``` bash
flang minimal.f90 
flang -mllvm --enable-affine-loop-opt minimal.f90 
loc("~/minimal.f90":5:3): error: error in fetching if analysis in AffineFunctionAnalysis
```
