tests: Mark NaN conversion as todo on NVIDIA.

Browse Source 
D3D mandates that NaN becomes zero when converted to unsigned[1],
while it doesn't look like that SPIR-V's OpConvertFToU has a similar
provision[2]. In practice, this seems to work on AMD and fails on
NVIDIA, where 0x80000000 is produced instead.
