[1/6] nvptx testsuite patches: alloca


This deals with uses of alloca in the testsuite. Some tests require it outright, others only at -O0, and others require it implicitly by requiring an alignment for stack variables bigger than the target's STACK_BOUNDARY. For the latter I've added explicit xfails.
