All usages of isSubRegionOf separately check for reflexive case, and in
any case, set theory tells us that each set is a subset of itself.

Added new enum in order to differentiate the warning messages on "misusing" into
3 categories: function calls, moving an object, copying an object. (At the
moment the checker gives the same message in case of copying and moving.)
Additional test cases added as well.

An earlier solution from Artem r315301 solves the reset problem, however, the
reports should be handled the same way in case of method calls. We should not
just report the base class of the object where the method was defined but the
whole object.
Fixed false positive which came from not removing the subobjects in case of a
state-resetting function. (Just replaced the State->remove(...) call to
removeFromState(..) which was defined exactly for that purpose.)
Some minor typos fixed in this patch as well which did not worth a whole new
patch in my opinion, so included them here.

If a method is resetting the state of an object that was moved from, it should
be safe to use this object again. However if the method was defined in a parent
class, but used in a child class, the reset didn't happen from the checker's
perspective.

This method injects additional information into program state dumps,
describing which objects have been moved from.

The checker currently warns on copying, moving, or calling methods on an object
that was recently std::move'd from. It understands a set of "state reset"
methods that bring a moved-from object back to a well-specified state.
