Remove assumptions that not-equals operators cannot be in any opclass. get_op_btree_interpretation assumed this in order to save some duplication of code, but it's not true in general anymore because we added <> support to btree_gist. (We still assume it for btree opclasses, though.)
Also, essentially the same logic was baked into predtest.c. Get rid of that duplication by generalizing get_op_btree_interpretation so that it can be used by predtest.c. Per bug report from Denis de Bernardy and investigation by Jeff Davis, though I didn't use Jeff's patch exactly as-is. Back-patch to 9.1; we do not support this usage before that.
