Using a name and setting the binding scope to "section scope" is similar to
using " " as name and leaving the binding scope unspecified.
The XLC and Open XL compilers provide a command line option to change this name
(XLC: `-qcsect`, `-qnocsect`; Open XL: `-mcsect`, `-mnocsect`). The Open XL
compiler defaults to the variant coded here but that can be changed to having a
name with binding scope unspecified (`-mcsect=a`) or set to space (`-mnocsect`).
Using `-mcsect=a` results in exactly the problem you describe.
The compiler option will be added later to clang, along with the required code
here.
The front end (aka clang) provides this value in the `source_filename`
property. All strings in LLVM/clang are in UTF-8 so there is no other choice.
The same problem arises for symbols derived from function names etc.
