    Make RegExpFlagsFromString faster · 2cce5c52
    Jakob Kummerow authored
    The new ObjectPtr design makes non-inlined helper functions a little
    more expensive because "this" is always a pointer where pass-by-value
    would be more efficient, which is an issue for functions whose size puts
    them right at the threshold of getting inlined or not. String::Get falls
    into this category when called from RegExpFlagsFromString. In this case,
    we can do even better than restoring inlineability by fine-tuning
    the control flow a bit.
    
    This should repair the regression in crbug.com/910573
