In `flang/lib/Evaluate/fold-integer.cpp` ca. line 1340 is the code that folds (underscore underscore) `builtin_numeric_storage`.  It defers that folding today until the reference to that intrinsic function is coming from a module file, at which point the size of a default numeric storage unit must be known.  If you're changing things so that `ISO_FORTRAN_ENV` is now going to be compiled with the size of a default numeric storage unit being well-defined, then you can probably just remove the code that defers the folding.
