add a hash_set based on hash_table

This allows us to replace the usage of pointer_set outside of
pointer_map with a nicer interface.

gcc/ada/

	* gcc-interface/trans.c: Use hash_set instead of pointer_set.

gcc/c-family/

	* c-gimplify.c: Use hash_set instead of pointer_set.

gcc/c/

	* c-decl.c: Use hash_set instead of pointer_set.

gcc/cp/

	* class.c, cp-gimplify.c, cp-tree.h, decl.c, decl2.c, error.c,
	method.c, name-lookup.c, pt.c, semantics.c, tree.c: Use hash_set
	instead of pointer_set.

gcc/fortran/

	* openmp.c, trans-decl.c: Use hash_set instead of pointer_set.

gcc/

	* hash-set.h: new File.
