gh-89973: Fix re.error in the fnmatch module. (GH-93072) 
Character ranges with upper bound less that lower bound (e.g. [c-a])
are now interpreted as empty ranges, for compatibility with other glob
pattern implementations. Previously it was re.error.
(cherry picked from commit 0902c3d8ed)

by joining multiple translate() results via `|`.

bpo-40480 "fnmatch" exponential execution time (GH-19908) 
bpo-40480:  create different regexps in the presence of multiple `*`
patterns to prevent fnmatch() from taking exponential time.

bpo-32775: Fix regular expression warnings in fnmatch. (#5583) 
fnmatch.translate() no longer produces patterns which contain set
operations.

Sets starting with '[' or containing '--', '&&', '~~' or '||' will
be interpreted differently in regular expressions in future versions.
Currently they emit warnings. fnmatch.translate() now avoids producing
patterns containing such sets by accident.

Serhiy Storchaka bd48d27944 Issue #22493: Inline flags now should be used only at the start of the 
regular expression.  Deprecation warning is emitted if uses them in the
middle of the regular expression.

Raymond Hettinger 5b0c1e07ca Issue 7846: fnmatch cache can grow without bound 
Updated to solution to use the functools.lru_cache().
Restores the API so that purge() is not needed
(because the cache never gets big).
