Fix min/max signed zero and NaN handling. Make min(x, y) equal to (x < y ? x : y) and max(x, y) equal to (x > y ? x : y), including the behavior for signed zeros and NaNs. This also enables optimizing them into min and max SSE2 instructions on x86.

SwiftShader is a high-performance CPU-based implementation of the OpenGL ES and Direct3D 9 graphics APIs12. Its goal is to provide hardware independence for advanced 3D graphics.
The SwiftShader libraries act as drop-in replacements for graphics drivers.
On Windows, most applications can be made to use SwiftShader's DLLs by placing them in the same folder as the executable. On Linux, the LD_LIBRARY_PATH environment variable or -rpath linker option can be used to direct applications to search for shared libraries in the indicated directory first.
