  1. Remove redundant -cl-unsafe-math-optimizations option. 

    OpenCL spec (https://www.khronos.org/registry/OpenCL/sdk/1.2/docs/man/xhtml/clBuildProgram.html) says that "cl-unsafe-math-optimizations" option allows a lot of optimizations and generated source code of Add<N> tests can be completely optimized out. E.g.
 s0=10.f-s0;
 s0=10.f-s0;
can be optimized to
s0=s0;
when -cl-unsafe-math-optimizations is specified. At least clang compiler started to eliminate this code a time ago.

It seems for this trivial test the option should be removed in order to avoid such optimizations.
