Similar to #2219, we see "'fpclassify': ambiguous call" error in test_conformance\basic\test_fpmath.cpp due to missing constexpr at https://github.com/KhronosGroup/OpenCL-CTS/blob/9265cbb2c274/test_conformance/basic/test_fpmath.cpp#L104 This PR fixes the issue by moving utility function isnan_fp in testHarness.h and use it. Note this PR doesn't modify use of isnan in many tests where only float/double values are checked.
