i965: Add an INTEL_DEBUG=no16 option.
Often when debugging, I don't want to see SIMD16 shaders. It makes INTEL_DEBUG=vs/fs output much easier to read, especially when a program dumps many shaders. Plus, I also want to verify that SIMD8 works before even considering SIMD16. v2: Fix the likeliness check (caught by Chris and Eric). Reviewed-by: Eric Anholt <[email protected]>
