Runtime fixes for the Java back-end.

java/runtime/DuExistLocn.java:
java/runtime/DuFunctorDesc.java:
java/runtime/DuPtagLayout.java:
	Define constructors for these types.

java/runtime/MaybeResAddrFunctorDesc.java:
	New file (corresponds to MR_MaybeResAddrFunctorDesc type in C).

java/runtime/MaybeResFunctorDesc.java:
	New file (corresponds to MR_MaybeResFunctorDesc type in C).

java/runtime/PseudoTypeInfo.java:
	Define constructors.
	Make non-abstract (XXX temp work-around only).

java/runtime/TypeCtorInfo_Struct.java:
	XXX Pass some parameters of the constructor as "Object",
	to work around type errors in invocations of those constructors.

java/runtime/TypeFunctors.java:
java/runtime/TypeLayout.java:
	Model the C unions better; use a single field, with accessor
	functions that convert to each alternative, not several fields.

java/runtime/TypeclassInfo.java:
	Implement as stub (previous code was just copy of TypeInfo.java).

java/runtime/VA_PseudoTypeInfo_Struct*.java:
	Fix a bug: change the order of the constructor parameters
	to match the way we generate code which invokes those constructors.
