New description:

 Currently, some classes define a {{{_gcd}}} method which is called by a
 {{{gcd}}} method of euclidean domain elements. Most elements already
 define {{{gcd}}} directly, and I see no real use in having this method in
 between.

 The attached patch renames all {{{_gcd}}} methods to {{{gcd}}} and also
 streamlines the use of {{{@coerce_binop}}} on them.

 This is similar to #13628.
