This change fixes issues #15240, which I filed earlier. It's a check to ensure that any file being compiled cannot be assigned an output file with the same name as the source implicitly.
For instance,
rustc myfilewould before overwrite myfile with the binary of itself. Now, the compiler sees this as an error, unless the compiler is given a directive to overwrite the file via the -o flag.
