--- Comment #1 from Alexander Kornienko <alexfh at google.com> ---
Clang-tidy can run any Clang diagnostic and apply suggested fixes if the
diagnostic produces them. The -Wignored-qualifiers can produce fixes, you can
use it in clang-tidy like this:

$ cat q.cc
const int f() { return 42; }
$ clang-tidy -extra-arg=-Wignored-qualifiers -fix q.cc --
1 warning generated.
q.cc:1:1: warning: 'const' type qualifier on return type has no effect
[clang-diagnostic-ignored-qualifiers]
const int f() { return 42; }
^
q.cc:1:1: note: FIX-IT applied suggested code changes
const int f() { return 42; }
^
clang-tidy applied 1 of 1 suggested fixes.
$ cat q.cc
int f() { return 42; }
