    ima: Fix fall-through warnings for Clang
    
    [ Upstream commit 28073eb09c5aa29e879490edb88cfd3e7073821e ]
    
    In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple
    warnings by explicitly adding multiple break statements instead of just
    letting the code fall through to the next case.
