INADA Naoki c1c47c166b bpo-31671: re: Convert RegexFlag to int before compile (GH-3862) 
sre_compile does bit test (e.g. `flags & SRE_FLAG_IGNORECASE`) in loop.
`IntFlag.__and__` and `IntFlag.__new__` made it slower.

So this commit convert it to normal int before passing flags to `sre_compile()`.

Serhiy Storchaka 898ff03e1e bpo-30215: Make re.compile() locale agnostic. (#1361) 
Compiled regular expression objects with the re.LOCALE flag no longer
depend on the locale at compile time.  Only the locale at matching
time affects the result of matching.

Victor Stinner fb6a6596b5 Issue #28637: Reapply changeset 223731925d06 
"issue28082: use IntFlag for re constants" by Ethan Furman.

The re module is not more used in the site module and so adding "import enum"
to re.py doesn't impact python_startup benchmark anymore.

Victor Stinner 1ec1cd161b Issue #28637: Revert issue #28082, don't import enum in re 
Importing the enum module in the re module slows down Python startup by 34%
when Python is run from a virtual environment, or more generally when the re
module is imported at startup but not the enum module.
