   3. Register allocation
   4. Generating assembly code

This patch splits out step 4 into a separate class named "vec4_generator."

There are several reasons for doing so:

   1. Future hardware has a different instruction encoding.  Splitting
      this out will allow us to replace vec4_generator (which relies
      heavily on the brw_eu_emit.c code and struct brw_instruction) with
      a new code generator that writes the new format.

   2. It reduces the size of the vec4_visitor monolith.  (Arguably, a lot
      more should be split out, but that's left for "future work.")

   3. Separate namespaces allow us to make helper functions for
      generating instructions in both classes: ADD() can exist in
      vec4_visitor and create IR, while ADD() in vec4_generator() can
      create brw_instructions.  (Patches for this upcoming.)

i965/fs: Split final assembly code generation out of fs_visitor.

Compiling shaders requires several main steps:

   1. Generating FS IR from either GLSL IR or Mesa IR
   2. Optimizing the IR
   3. Register allocation
   4. Generating assembly code

This patch splits out step 4 into a separate class named "fs_generator."

There are several reasons for doing so:

   1. Future hardware has a different instruction encoding.  Splitting
      this out will allow us to replace fs_generator (which relies
      heavily on the brw_eu_emit.c code and struct brw_instruction) with
      a new code generator that writes the new format.

   2. It reduces the size of the fs_visitor monolith.  (Arguably, a lot
      more should be split out, but that's left for "future work.")

   3. Separate namespaces allow us to make helper functions for
      generating instructions in both classes: ADD() can exist in
      fs_visitor and create IR, while ADD() in fs_generator() can
      create brw_instructions.  (Patches for this upcoming.)

Furthermore, this patch changes the order of operations slightly.
Rather than doing steps 1-4 for SIMD8, then 1-4 for SIMD16, we now:

   - Do steps 1-3 for SIMD8, then repeat 1-3 for SIMD16
   - Generate final assembly code for both modes together

This is because the frontend work can be done independently, but final
assembly generation needs to pack both into a single program store to
feed the GPU.
