Summary: There's some logic in the AMDGPU target that manually resets the requested visibility of certain variables. This was triggering when we set a constant variable in OpenMP. However, we shouldn't do this for OpenMP when the variable has the `nohost` type. That implies that the variable is not visible to the host and therefore does not need to be visible, so we should respect the original value of it.
