Any way to convert ModuleRef to Module?

I want to read in a `bitcode` or `llvmir` file, and convert the return value (ModuleRef) from `parse_bitcode` or `parse_assembly` to `Module`.

I checked the constructor of Module, there is no options to do this.

Start by tracing the parse_bitcode and parse_assembly entry points and comparing their ModuleRef return values with the Module constructor. Determine whether a supported conversion path is possible and define the expected behavior for reading bitcode or LLVM IR into Module. The issue is old and has no named files or tests, so further repository research is needed before implementation.
