Delete test cases that never run (#if 0 blocks, [NotWorking] cases, commented-out Perl ports, blocks behind undefined macros), cases that cannot fail, cases that only exercise boost::polygon directly, and cases whose assertions another test already makes on the same path. Remove the helpers, includes and fixture only those cases used.
