Fix math tests to allow ftz in relaxed mode. (#1371)

Browse Source 
* Fix math tests to allow ftz in relaxed mode.

In recent spec clarification, it is agreed that ftz is
a valid optimization in case of cl-fast-math-relaxed
and doesn't require cl-denorms-are-zero to be passed
explicitly to enforce ftz behavior for implementations
that already support this.
