This flags enables the compiler to generate most of the debug information in a separate file which can be useful for executable size and link times. Clang already supports this flag. I have tried to follow the logic of the clang implementation where possible. Some functions were moved where they could be used by both clang and flang. The `addOtherOptions` was renamed to `addDebugOptions` to better reflect its purpose. Clang also set the `splitDebugFilename` field of the `DICompileUnit` in the IR when this option is present. That part is currently missing from this patch and will come in a follow-up PR.
