[issue31671] IntFlag makes re.compile slower

[Serhiy Storchaka]

I don't think there is a problem which is worth to be solved by PR 3867. It is very unlikely that anyone uses re functions with a pattern and float flags which accidentally matches already cached valid pattern and integer flag. If float value is passed as a flag it is likely is passed the first time. Fractional floats are rejected in any case. This is different from the problem with PR 3862.
