Controls the visibility of non-kernel functions when compiling for AMDGPU targets. Defaults to the default value visibility (-fvisibility), and is set in the AMDGPU toolchain to be "hidden" if not set explicitly.

This is a more fine-grained knob than "-fvisibility hidden", and allows the default visibility of functions to be controlled independent of kernels. This is useful for languages like OpenCL where kernel symbols are externally visible, but function symbols are not.
