32990	Test the tag_re regex in template/base.py instead of evaluating it every time	Chris Jerdonek	gtwohig	"I noticed that `template/base.py` has a somewhat complicated regex string at the top involving six calls to `re.escape()` that it needs to evaluate every time: https://github.com/django/django/blob/4fe3774c729f3fd5105b3001fe69a70bdca95ac3/django/template/base.py#L90-L93

A more efficient approach would be to define a hard-coded `_TAG_RE_REGEX` regex at the top that is the result of that substitution, and add a test checking that it matches the result of calling `re.escape()` six times, etc. That would eliminate the need to do the substitution at runtime.
