Handle new'ing of Java classes.

	Handle new'ing of Java classes.
	* init.c (build_class_classref):  New function.
	(build_new_1):  If type is TYPE_FOR_JAVA:  Call _Jv_AllocObject;
	constructor does not return this;  don't need to exception-protect.
	* pt.c (lookup_template_class):  Copy TYPE_FOR_JAVA flag.
	* decl2.c (acceptable_java_type):  Handle template-derived types.
