[PATCH] D39702: [test-suite] [CUDA] Delete nexttoward and nextafter CUDA tests, because these functions have no implementations.

These functions never actually worked -- if you called them, you'd get a
ptxas error when llvm tried to make a libcall to e.g. nexttowardf.

This test only compiled because the calls were DCE'ed.  Sadly my
laziness in not checking the return value of these functions resulted in
this long-standing bug.

On the upside, we check the return values of all other math functions,
so this bug is limited to nexttoward and nextafter.
