	Force left-to-right evaluation of binary operations etc.
	* expr.c (force_evaluation_order), java-tree.h:  New function.
	* parse.y (java_complete_lhs):  Pass binary operations, procedure
	calls, and ARRAY_REFs to force_evaluation_order.
	(various):  Set TREE_SIDE_EFFECTS more carefully.
	Tolerate random (non-UTF8) encoding in comments without complaining.
	* lex.c (java_read_char):  Return 0xFFFE if bad UTF8 encoding.
	(java_is_eol):  Handle '\r' followed by '\n' instead of vice versa.
	* parse.y (resolve_qualified_expression_name):  Handle error_mark.
	(java_complete_node case EXPR_WITH_FILE_LOCATION):  Likewise.
	* parse.y (java_complete_lhs):  Ignore an empty statement in a
	COMPOUND_EXPR.  Don't complain about empty statement after return.
