Jason Ekstrand	10adf8fc85	nir: Differentiate between signed and unsigned versions of find_msb ... We also make the return types match GLSL. The GLSL spec specifies that findMSB and findLSB return a signed integer. Previously, nir had them return unsigned. This updates nir's behavior to match what GLSL expects. We also update the nir-to-fs generator to take the new instructions. While we're at it, we fix the case where the input to findMSB is zero.
