The WinAPI `GetFinalPathNameByHandle` is used to retrieve the DLL file name from the HANDLE provided to `LOAD_DLL_DEBUG_EVENT` in the debug loop. When this API fails, lldb will simply ignore that module. Certain ramdisk (e.g. ImDisk) does not work with this API, which means it is impossible to use lldb to debug a process which loads DLLs located on this type of ramdisk. In order to make this work, we need to use a fallback routine which involves creating a file mapping, using `GetMappedFileName` to get a device path, then substitutes the device path with its drive letter.
