  Similarly, operator_bitwise_and::fold_range with prange arguments 
supercedes  the pointer_and_operator class, so this patch removes the 
class to avod any confusion.

Bootstraps on x86_64-pc-linux-gnu with no regressions.  pushed.

Subject: [PATCH 3/4] Remove pointer_and_operator.

This operator class predates the dispatch system, and is no longer used.
The functionality of wi_fold has been replaced by
operator_bitwise_and::fold_range with prange operaands.

	* range-op-ptr.cc (class pointer_and_operator): Remove.
	(pointer_and_operator::wi_fold): Remove.
