shapes-ISSUE-143 (pre-binding in core): more pre-binding is needed in Section 3 [SHACL - Core]

http://www.w3.org/2014/data-shapes/track/issues/143

Raised by: Peter Patel-Schneider
On product: SHACL - Core

The SHACL code in Section 3 depends on parameter pre-binding, but there is no support for parameter pre-binding in the core sections.

For example, according to the leadup to Section 3.1.1 $class would be unbound (or unsubstituted) when the code for sh:ClassConstraintComponent is run

SELECT $this ($this AS ?subject) $predicate (?value AS ?object)
WHERE {
	$this $predicate ?value .
	FILTER NOT EXISTS { ?value rdf:type/rdfs:subClassOf* $class } .
}
