84963d6833 intel/brw: Take shader in the brw_generator::generate_code() parameters

6ca9021758 brw: Add brw_shader_params 
And unify the initialization code for brw_shader.  Avoid passing
brw_compile_params since for a single compilation we might have
multiple shaders (the case for BS stage).

46c16f854e brw: compute consistent clip/cull distance masks with VUE 
We can optimize the VUE layout in cases where all shaders are compiled
together and some outputs are unused. So we need to have consistent
clip/cull_distance_mask with the VUE.

Previously we could have a VUE without ClipDistance present in the
header and yet have a non zero clip_distance_mask. This would trip the
HW into taking into account a VUE field that doesn't exist.

Here we set the clip/cull_distance_mask to 0 if the associated output
is not written by the shader. The written outputs are always
consistent with what's in the VUE.

8e2a7cb42d brw: Embed at_end() inside brw_builder(brw_shader *) constructor 
All remaining uses of that constructor would also use at_end(),
and vice-versa.  So just implement that behavior in the constructor
itself.

5ca23eff0b intel/brw: Remove brw_gs_compile struct 
There were 4 fields:

- key: now will be passed explicitly, so we can reuse the existing
  more general fs_visitor constructor;

- input_vue_map: used only by the client code brw_compile_gs, so
  create it separatedly as a local variable;

- two unsigned parameters: just put them inside a nested struct in the
  shader.

70fecb1483 intel/brw: Report number of GRF registers used in brw_stage_prog_data. 
This is similar to what we used to do on pre-SNB platforms, the number
of GRF registers used by the shader will be used on Xe3+ to adjust the
trade-off between thread-level parallelism and size of the GRF file.
Plumb the value through prog_data so the driver can set up the
hardware state accordingly.
