Prior to this patch, when comparing the paths of source files in Dexter commands, we would use os.samefile. This function performs actual file operations and requires the files to exist on the current system; this is suitable when running the test for the first time, but renders the DextIR output files non-portable, and unusable if the source files no longer exist in their original location.
