i965: Allocate just enough space for user clip planes in uniform arrays.

Previously, we allocated space in brw_vs_prog_data's params and
pull_params arrays for MAX_CLIP_PLANES vec4s---even when it wasn't
necessary.

On a 64-bit architecture, this used 0.5 kB of space (8 clip planes *
4 floats per plane * 8 bytes per float pointer * 2 arrays of pointers =
512 bytes).  Since this cost was per-vertex shader, it added up.

Conveniently, we already store the number of clip plane constants in the
program key.  By using that, we can allocate the exact amount of space
needed.  For the common case where user clipping is disabled, this means
0 bytes.

While we're here, mention exactly what code requires this extra space,
since it wasn't obvious.

i915: Optimize SEQ and SNE when two operands are uniforms

SEQ and SNE are not native i915 instructions, so they each generate at

get 5 instructions like:

                R[0].xyz = MUL R[0], U[0]

This code is stupid.  Instead of having the individual calls to
i915_emit_arith generate the moves to utemps, do it in the caller.  This
results in code like:

                R[0].xyz = MUL R[0], U[0]

This allows fs-temp-array-mat2-index-col-wr and
fs-temp-array-mat2-index-row-wr to fit in hardware limits (instead of
falling back to software rasterization).

i965: Allow C++ type safety in the use of enum brw_urb_write_flags.

(From a suggestion by Francisco Jerez)

If an enum represents a bitfield of flags, e.g.:

enum E {
  A = 1,
  B = 2,
  C = 4,
  D = 8,
};

then C++ normally prohibits statements like this:

enum E x = A | B;

because A and B are implicitly converted to ints before OR-ing them,
and an int can't be stored in an enum without a type cast.  C, on the
other hand, allows an int to be implicitly converted to an enum
without casting.

In the past we've dealt with this situation by storing flag bitfields
as ints.  This avoids ugly casting at the expense of some type safety
that C++ would normally have offered (e.g. we get no warning if we
accidentally use the wrong enum type).

However, we can get the best of both worlds if we override the |
operator.  The ugly casting is confined to the operator overload, and
we still get the benefit of C++ making sure we don't use the wrong
enum type.

i965/gs: add GS visitors.

This patch introduces the vec4_gs_visitor class, which translates
geometry shaders from GLSL IR to back-end opcodes.

This class is derived from vec4_visitor (which is also the base class
for vec4_vs_visitor), so as a result most of the back end code is
shared.  The only parts that differ are:

- Geometry shaders use a different input payload organization, since
  the inputs need to match up with the outputs of the previous
  pipeline stage (vec4_gs_visitor::setup_payload() and
  vec4_gs_visitor::setup_varying_inputs()).

- Geometry shader input array dereferences need a special stride
  computation, since all geometry shader inputs are interleaved into
  one giant array (vec4_gs_visitor::compute_array_stride()).

- There are no geometry shader system values
  (vec4_gs_visitor::make_reg_for_system_value()).

- At the beginning of a geometry shader, extra data in R0 needs to be
  zeroed out, and a vertex counter needs to be initialized
  (vec4_gs_visitor::emit_prolog()).

- When EmitVertex() appears in the shader, the current contents of
  output variables need to be emitted to the URB, and the vertex
  counter needs to be incremented
  (vec4_gs_visitor::visit(ir_emit_vertex *)).

- When generating a URB_WRITE message to output vertex data, the
  current state of the vertex counter needs to be used to store a
  write offset in the message header
  (vec4_gs_visitor::emit_urb_write_header()).

- The URB_WRITE message that outputs vertex data needs to be sent
  using GS_OPCODE_URB_WRITE, since VS_OPCODE_URB_WRITE would overwrite
  the offsets in the message header
  (vec4_gs_visitor::emit_urb_write_opcode()).

- At the end of a geometry shader, the final vertex count needs to be
  delivered using a URB WRITE message
  (vec4_gs_visitor::emit_thread_end()).

- EndPrimitive() functionality is not implemented yet
  (vec4_gs_visitor::visit(ir_end_primitive *)).

- There is no support for assembly shaders
  (vec4_gs_visitor::emit_program_code()).

v2: Make num_input_vertices const.  Refer to registers as rN rather
than gN, for consistency with the PRM.  Fix misspelling.  Improve
comment in the ir_emit_vertex visitor explaining why we emit vertices
inside a conditional.  Enclose the conditional code in the
ir_emit_vertex visitor between curly braces.

i965/vec4: Virtualize setup_payload instead of setup_attributes.

When I initially generalized the vec4_visitor class in preparation for
geometry shaders, I assumed that the setup_attributes() function would
need to be different between vertex and geometry shaders, but its
caller, setup_payload(), could be shared.  So I made
setup_attributes() a virtual function.

It turns out this isn't true; setup_payload() needs to be different
too, since the geometry shader payload sometimes includes an extra
register (primitive ID) that has to come before uniforms.

So setup_payload() needs to be the virtual function instead of
setup_attributes().

i965/vec4: Allow for dispatch_grf_start_reg to vary.

Both 3DSTATE_VS and 3DSTATE_GS have a dispatch_grf_start_reg control,
which determines the register where the hardware delivers data sourced
from the URB (push constants followed by per-vertex input data).

For vertex shaders, we always set dispatch_grf_start_reg to 1, since
R1 is always the first register available for push constants in vertex
shaders.

For geometry shaders, we'll need the flexibility to set
dispatch_grf_start_reg to different values depending on the behvaiour
of the geometry shader; if it accesses gl_PrimitiveIDIn, we'll need to
set it to 2 to allow the primitive ID to be delivered to the thread in
R1.

This patch eliminates the assumption that dispatch_grf_start_reg is
always 1.  In vec4_visitor, we record the regnum that was passed to
vec4_visitor::setup_uniforms() in prog_data for later use.  In
vec4_generator, we consult this value when converting an abstract
UNIFORM register to a concrete hardware register.  And in the code
that emits 3DSTATE_VS, we set dispatch_grf_start_reg based on the
value recorded in prog_data.

This will allow us to set dispatch_grf_start_reg to the appropriate
value when compiling geometry shaders.  Vertex shaders will continue
to always use a dispatch_grf_start_reg of 1.

v2: Make dispatch_grf_start_reg "unsigned" rather than "GLuint".

i965: Fix misapplication of gles3 srgb workaround

Fixes inconsistent failure of gles2conform/GL2Tests/glUniform/glUniform.test
under gnome-shell. What follows is a description of the bug and its fix.

When intel_update_renderbuffers() allocates a miptree for a winsys
renderbuffer, it propagates the renderbuffer's format to become also the
miptree's format.

If the winsys color buffer format is SARGB, then, in the first call to
eglMakeCurrent, intel_gles3_srgb_workaround() changes the renderbuffer's
format to ARGB. That is, it changes the format from sRGB to non-sRGB.
However, it changes the renderbuffer's format *after*
intel_update_renderbuffers() has allocated the renderbuffer's miptree.
Therefore, when eglMakeCurrent returns, the miptree format (SARGB)
differs from the renderbuffer format (ARGB).

If the X server reallocates the color buffer,
intel_update_renderbuffers() will create a new miptree for the
renderbuffer. The new miptree's format (ARGB) will differ from old
miptree's format (SARGB). This mismatch between old and new miptrees
causes bugs.

Fix the bug by moving intel_gles3_srgb_workaround() to occur *before*
intel_update_renderbuffers().
