`std::exception` and `std::runtime_error` are polymorphic types and as
such they shouldn't be passed by value.

* 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
Spir test compares floating-point kernel results bit-by-bit with
correct results. However, for math_brute_force kernels, specification
does not ask for SPIR and OpenCL C path to match bit-to-bit. This patch
reuses ulps threshold from math_brute_force folder for math_brute_force
kernels in spir test.
