Forbid `//@ compile-flags: -Cincremental=` in tests
Tests should not try to manually enable incremental compilation with `-Cincremental`, because that typically results in stray directories being created in the repository root. Instead, use the `//@ incremental` directive, which instructs compiletest to handle the details of passing `-Cincremental` with a fresh directory.
