I was thinking about the same issue and tried to see if this information is parameterized somewhere. But I found that `LLVMTypeConverter` [here](https://github.com/llvm/llvm-project/blob/98e3075df992636fa42aafde96748d1d5c834688/flang/lib/Optimizer/CodeGen/TypeConverter.cpp#L132) seems to always use the 64-bit for the index type so used the same logic.
