remove tests from really old regex module

-# Regex test suite and benchmark suite v1.5a2
-
-# The 3 possible outcomes for each pattern
-[SUCCEED, FAIL, SYNTAX_ERROR] = range(3)
-
-# Benchmark suite (needs expansion)
-#
-# The benchmark suite does not test correctness, just speed.  The
-# first element of each tuple is the regex pattern; the second is a
-# string to match it against.  The benchmarking code will embed the
-# second string inside several sizes of padding, to test how regex
-# matching performs on large strings.

-# Test suite (for verifying correctness)
-#
-# The test suite is a list of 5- or 3-tuples.  The 5 parts of a
-# complete tuple are:
-# element 0: a string containing the pattern
-#         1: the string to match against the pattern
-#         2: the expected result (SUCCEED, FAIL, SYNTAX_ERROR)
-#         3: a string that will be eval()'ed to produce a test string.
-#            This is an arbitrary Python expression; the available
-#            variables are "found" (the whole match), and "g1", "g2", ...
-#            up to "g10" contain the contents of each group, or the
-#            string 'None' if the group wasn't given a value.
-#         4: The expected result of evaluating the expression.
-#            If the two don't match, an error is reported.
-#
-# If the regex isn't expected to work, the latter two elements can be omitted.
