Comment at: clang/test/CodeGenOpenCL/relaxed-fpmath.cl:14
   // FINITE: fdiv nnan ninf float
-  // UNSAFE: fdiv nnan nsz float
+  // UNSAFE: fdiv reassoc nsz arcp afn float
   // MAD: fdiv float
----------------
This change is based on the following:
* `-cl-fast-relaxed-math` = `-cl-unsafe-math-optimizations` + `-cl-finite-math-only` 
* the GCC option `-funsafe-math-optimizations` and `-cl-unsafe-math-optimizations` are described with very similar wording and from the GCC description states explicitly mention that no signed zeros, reassociation and reciprocals are enabled, but there is no mention to assuming that NaNs do not exist.
