xsltTestCompMatchDirect: @ctxt: a XSLT process context @comp: the precompiled pattern @node: a node @nsList: the namespaces in scope @nsNr: the number of namespaces in scope

Test whether the node matches the pattern, do a direct evalutation and not a step by step evaluation.

Returns 1 if it matches, 0 if it doesn't and -1 in case of failure
