SPIRV-Cross/spirv_cross_c.cpp
Hans-Kristian Arntzen 31be74a853 Add relax_nan_checks options. 
Makes codegen from typical D3D emulation SPIR-V more readable.
Also makes cross compilation with NotEqual more sensible.
It's very rare to actually need the strict NaN-checks in practice.

Also, glslang now emits UnordNotEqual by default it seems, so give up
trying to assume OrdNotEqual. Harmonize for UnordNotEqual as the sane
default.
