[m-rev.] HLC backend speedup for N-queens

[fabrice nicol]

Hi Julien,

attached are the benchmark files named along the following pattern: 
queens_platforms.ext

C++ programs were compiled with GNU g++-10.2 using -O3 -march=native.

FYI, I'm currently working on an R interface library for Mercury, a bit 
like the 'real' package for swi/yap but more straightforward thanks to 
the Mercury C backend.

Preliminary results are surprisingly good and harnessing R C/C++/Fortran 
statistical/data processing libraries into Mercury looks like a credible 
prospect. I'll be coming back within a month with further results 
(unless this has already been done somewhere. If so, please let me know).
