commit 0c93bc3bb824ea31c21c6c7bdead9aa781e154ba
Author: Herbert Valerio Riedel <hvr at gnu.org>

    Fix misattribution of `-Wunused-local-binds` warnings
    
    This fixes a bug where warnings actually controlled by
    
    - `Opt_WarnUnusedMatches`
    - `Opt_WarnUnusedTypePatterns`
    - `Opt_WarnUnusedTopBinds`
    
    were incorrectly reported as being controlled by
    `Opt_WarnUnusedLocalBinds` as well
    
    This bug was introduced in bb5afd3c274011c5ea302210b4c290ec1f83209c
    while implementing #10752
    
    Test Plan: ./validate still running -- testsuite output wiggles expected
