When importing from LLVM IR the data layout of all pointer types contains an index bitwidth that should be used for index computations. This revision adds a getter to the DataLayout that provides access to the already stored bitwidth. The function returns an optional since only pointer-like types have an index bitwidth. Querying the bitwidth of a non-pointer type returns std::nullopt. The new function works for the built-in Index type and, using a type interface, for the LLVMPointerType.
