It appears these SPIR-V extension functions don't behave as they should

They're supposed to be NaN-aware such that if one argument is NaN, the
other argument is returned. From our testing, it looks like NMax works
as expected, but not NMin or NClamp.
Do you have some specific test cases that fail?
Yeah, but they come from WHCK and I don't have a small test case.
I'll try your patch series and see what happens.

I'm using your patch and I'm also making use of
VK_KHR_shader_float_control but neither has helped. Though, the later
does help with some issues in Nvidia.
