SPIR-V intsruction selection was mapping the LLVM float min/max intrinsics to FMin and FMax respectively for GL/Vulkan environments, which does not match the intrinsics' documented treatment of NaN operands. This patch switches the mapping to the correctly matched NMin and NMax operations. Fixes #87072
