4 This test serves two purposes:
5 
6 (1) It documents all existing warnings that currently have no associated -W flag,
7     and ensures that the list never grows.
8 
9     If you take an existing warning and add a flag, this test will fail.
10     To fix this test, simply remove that warning from the list below.
11 
12 (2) It prevents us adding new warnings to Clang that have no -W flag.  All
13     new warnings should have -W flags.
14 
15     If you add a new warning without a flag, this test will fail.  To fix
16     this test, simply add a warning group to that warning.
17 
18 
19 The list of warnings below should NEVER grow.  It should gradually shrink to 0.
