Since sm_6_5 is the new default, remove the -use-dxil option, add -use-dxcb option Remove -use-dxil option from all test cases. Add -use-dxcb to two tests that needed it.

The previous implementation is incorrect and basically only works in the `x = 0` case. `delta` was the smallest possible positive value representable as a float, but that's below the rounding error of addition with almost all reasonably sized floats. This fixed implementation is based on bit twiddling instead. I've checked the float case against the C++ `nextafterf` with both a -inf -> inf and inf -> -inf sweep, in addition to the test included in this PR.
