... this fixes the last remaining compile fail for libstdc++ in parallel

This is necessary from bits/stl_algobase.h line 901:

 if (*__first1 < *__first2)
	    return true;
 if (*__first2 < *__first1)

The fix is to put in an operator< for both arguments for the
two-argument __gnu_parallel::less, and to add a partial specialization
for single-argument __parallel::less, to avoid ambiguity when the
arguments are of the same type.

I'd actually put this in earlier drafts, but taken it out by mistake.
