Bugs from uncompyle6's 3.3 bytecode test suite

[rocky]

Even if these bugs are not likely to ever be addressed, there's value in recording what kinds of bugs are there.

These probably should be broken out into one issue per bug, and some might turn out to be duplicates, but since there's little chance of any getting fixed, I'm reducing the reporting effort.

# In Python 3.3+ this uses grammar rule
# compare_chained2 ::= expr COMPARE_OP RETURN_VALUE

# Seen in Python 3.3 ipaddress.py

def _is_valid_netmask(netmask):
    return 0 <= netmask <= 10

# There were also bugs in 2.6- involving the use of "or" twice in its "or"
# detections

# See in 2.6.9 quopri.py ishex():
'0' <= __file__ <= '9' or 'a' <= __file__ <= 'f' or 'A' <= __file__ <= 'F'
