gallivm: fix float->SNORM conversion
Just like the UNORM case we need to use round to nearest, not trunc. (There's also another problem, we're using the formula for SNORM->float which will produce a value below -1.0 for the most negative value which according to both OpenGL and d3d10 would need clamping. However, no actual failures have been observed due to that hence keep cheating on that.) Reviewed-by: Jose Fonseca <jfonseca@vmware.com>
