    • compiler: Don't crash on invalid arithmetic ops. · 8a256400 
          
    The gofrontend would crash after hitting an unreachable state while
    trying to determine the type of an arithmetic expression involving
    non-numeric values.  Instead of crashing, it should fail gracefully
    if the relevant error is already reported.
    
    Fixes golang/go#11537.
