[issue42915] enum.Flag ~ bitwise negation is very slow and can't be defined as a Flag value

I just finished a rewrite of Flag for 3.10.  Using your test below I was able to tweak the rewrite so the final numbers are:

Took normal 0.148092 seconds.
Took cached 0.017438 seconds.

Your original post had a ratio of nearly 200 -- it is now 8.7ish.
