RUN: diagtool list-warnings > %t 2>&1
RUN: FileCheck --input-file=%t %s

This test serves two purposes:

(1) It documents all existing warnings that currently have no associated -W flag,
    and ensures that the list never grows.

    If you take an existing warning and add a flag, this test will fail.
    To fix this test, simply remove that warning from the list below.

(2) It prevents us adding new warnings to Clang that have no -W flag.  All
    new warnings should have -W flags.

    If you add a new warning without a flag, this test will fail.  To fix
    this test, simply add a warning group to that warning.


The list of warnings below should NEVER grow.  It should gradually shrink to 0.
