We can get the result type information easily from nir_tex_instr itself
by looking at dest_type. There's no reason to construct a vector and
try to index into it.

This one's a bit more complex because it filters off only those
variables with mode == nir_var_uniform. As such, it's not exactly a
drop-in replacement for nir_foreach_variable(var, &nir->uniforms).

Make use of the live range evaluation to merge registers. Since the
live ranges are evaluated for register indices, the algorithm is not
optimal, but for most piglits up to glsl-3.3 it does the job.

This commit adds support for vertex and fragment shaders from NIR, and
support for most TEX and ALU instructions.
Thanks Dave Airlied for adding support for a number of ALU instructions.
v2: fix compilation with gcc-6
v3: rebase: use mesa/core glsl_type_size function
