Re: Decimal: Formal review begins

I mentioned this to Matt, but I would like to see benchmarks comparing
boost::decimal64_fast to a Decimal64 backed by Intel's DFP library, which
is what I know to be in actual use today:

https://www.intel.com/content/www/us/en/developer/articles/tool/intel-decimal-floating-point-math-library.html

Not that the benchmarks comparing to GCC's Decimal64 (which is based on the
libbid which ships with libgcc) aren't useful, I personally don't know
anyone using that today.

Benchmarks should ideally also include Intel's compiler, because at least
one of the relevant parties who motivated me to suggest the Decimal64
library (to Vinnie as a potential project) do use the Intel C++ compiler
(and their Fortran compiler) for areas where they perform better.

(The non-fast versions don't matter to me. I don't know anyone who would
want to use them).
