Basic conformance testing for the cl_khr_device_uuid extension. Checks
that the ID queries return the right sizes and that the returned IDs are
stable across two calls to clGetDeviceInfo. If device LUID validity is
true, also checks that one and only one bit is set in the device node
mask.

* Enable -Werror for GCC/Clang builds
Fixes many of the errors this produces, and disables a handful that
didn't have solutions that were obvious (to me).
* Check for `-W*` flags empirically
* Remove cl_APPLE_fp64_basic_ops support
* Undo NAN conversion fix
* Add comments to warning override flags
* Remove unneeded STRINGIFY definition
* Fix tautological compare issue in basic
* Use ABS_ERROR macro in image tests
* Use fabs for ABS_ERROR macro
* Move ABS_ERROR definition to common header
