* compar.c (cmp_equal): remove error hiding in Comparable#==.
  Comparable#== no longer rescues exceptions silently.
  This was the cause of quite a couple bugs. See #7688. [EXPERIMENTAL]
* test/ruby/test_comparable.rb: adapt assertion to match new behavior.
* lib/rdoc/method_attr.rb: fix bugs discovered by this change.
* test/rdoc/test_rdoc_normal_class.rb: fix bugs in tests.
