Rename support._match_test() to support.match_test(): make it
public
Remove support.match_tests global variable. It is replaced with a
new support.set_match_tests() function, so match_test() doesn't
have to check each time if patterns were modified.
Rewrite match_test(): use different code paths depending on the
kind of patterns for best performances.
