[V3 PATCH] rel_ops in backwards-compat headers

[Phil Edwards]

For libstdc++, using the std::rel_ops operators causes serious problems
with other components of the library, so we no longer #include that header
in the main library headers.  But we didn't make the same change to the
backwards-compatability headers, thus causing compilation failures for
users playing mix-and-match games with old and new headers (which still
needs to work).

Applied to the head and the branch.  This fixes a number of PRs (some
already closed as duplicates).  Finally!  :-)

	* include/backward/function.h:  Do not use rel_ops for older
	  headers either.
	* include/backward/pair.h:  Likewise.
