9512	trivial bug: sign change for negative values in bessel_i1	Cornelia Strauß <strauss@…>	John Maddock	"The function `bessel_i1()` in `boost/math/special_functions/detail/bessel_i1.hpp` ends with the following code:

{{{#!python
if (x < 0)
{
    value *= -value;                 // odd function
}
return value;
}}}

Instead of taking the square root, only the sign of `value` should be changed:

{{{#!python
if (x < 0)
{
    value *= -1;                 // odd function
}
return value;
