pan/bi: Implement nir_op_vec8 and nir_op_vec16

Browse Source 
These are used with OpenCL, particularly with 8-bit types. Luckily, they are
pretty easy to implement with our existing infrastructure. We just need to hit
backspace enough times and we're good to go.

Fixes a subtest of test_basic hiloeo.
