ISPN-3307 Update EquivalentCHMv8 to rev 112 fixing StackOverflow issue

https://issues.jboss.org/browse/ISPN-3307

* Added a plain, vanilla CHMv8 to the testsuite to use it to verify
test failures against the base CHMv8 version versus the equivalent
version. This is useful to detect bugs in the equivalent modifications.
