12018	rounded_arith_opp doesn't work in Release configuration under msvc 14	peter.azmanov@…	Boris Gubenko	"Interval calculations with `rounded_arith_opp` in Release under msvc 14 result in zero-size intervals.

It seems that compiler optimizes too much, e.g. in
{{{
BOOST_UP_NEG(x / (-y));
}}}
it moves minus operation and calculates something like
{{{
BOOST_UP_NEG(-(x / y));
}}}
which returns the same result as
{{{
BOOST_UP(x / y);
}}}

It looks more like compiler bug. Attached patch is a workaround which solves the issue.

Tested on x64 platform with /fp:strict and /fp:precise under MS Visual Studio Community 2015 Version 14.0.24720.00 Update 1.
