ippsCopySign

I can't find an ippsCopySign function, corresponding to the copySign function, defined in sections 5.5.1 and 6.3 of the IEE-754.2008 standard. Neither did I find such a function in MKL. Apple Accelerate however has vvcopysign, vvcopysignf, vcopysignf and vsignbitf.

With a copySign function in place, other functions can subsequently be implemented in application code, like a signed power and other functions. So, copySign is really a required base function.
