Put a higher penalty on breaking before "." or "->".

This fixes llvm.org/PR14823.

Before:
    local_state->SetString(prefs::kApplicationLocale, parent_local_state
                                ->GetString(prefs::kApplicationLocale));
After:
    local_state->SetString(
        prefs::kApplicationLocale,
        parent_local_state->GetString(prefs::kApplicationLocale));
