* java-tree.h:  Redefine some macros and add soem declaration
	to handle the USE_MAPPED_LOCATION case.
	* parse.h (EXPR_WFL_QUALIFICATION):  Use operand 1, not 2.
	* java-tree.h (EXPR_WFL_FILENAME_NODE):  Use operand 2, not 1.
	* java-tree.def (EXPR_WITH_FILE_LOCATION): Only need two operands in
	USE_MAPPED_LOCATION case, since EXPR_WFL_FILENAME_NODE is gone.
