Subject: [OpenMP][CUDA] Add missing overload for `remquo(float,float,int*)`

[OpenMP][CUDA] Add missing overload for `remquo(float,float,int*)`

Reported by Colleen Bertoni <bertoni@anl.gov> after running the OvO test
suite: https://github.com/TApplencourt/OvO/

The template overload is still hidden behind an ifdef for OpenMP. In the
future we probably want to remove the ifdef but that requires further
testing.
