	PR java/8923
	* parse.y (build_incdec): Emit an error instead of an ICE if '++' or '--'
	is used with a constant operand.
	(java_complete_lhs): When processing a '++' or '--' expression, don't call
	java_complete_tree but java_complete_lhs, so that a static final variable
	operand is never replaced by its value. This avoids an ICE later on.
	(patch_unaryop): Fixed typo in comment.
