Back to basis, patch 6:
* revert changes on indexgroup and groupindex types: I will fix this later, once this issue is fixed
* pattern_richcompare() and pattern_hash() also uses pattern, but don't use groups, indexgroup nor groupindex anymore
I removed the @cpython_only unit test and rewrote test_pattern_compare_bytes() to make it easier to follow.
re.compile('abc', re.IGNORECASE) is different than re.compile('ABC', re.IGNORECASE), but it's a deliberate choice to not test it. I consider that the behaviour can change depending on the Python implementation and in a future version.
