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).
