i965 Gen6+: Invalidate VF address-based cache on flush

Although there is not much documentation of this fact, there are in
fact two separate VF caches:

- an "index-based" cache (described in the Sandy Bridge PRM, vol 2
  part 1, section 2.1.2 "Vertex Cache").  This cache stores URB
  handles of vertex shader outputs; its purpose is to avoid redundant
  invocations of the vertex shader when drawing in random access mode
  (e.g. glDrawElements()), and the same vertex index is specified
  multiple times.  It is automatically invalidated between
  3D_PRIMITIVE commands and between instances within a single
  3D_PRIMITIVE command.

- an "address-based" cache (mentioned briefly in vol 2 part 1, section
  1.7.4 "PIPE_CONTROL Command").  This cache stores the data read from
  vertex buffers; its purpose is to avoid redundant memory accesses
  when doing instanced drawing or when multiple 3D_PRIMITIVE commands
  access the same vertex data.  It needs to be manually invalidated
  whenever new data is written to a buffer that is used for vertex
  data.

Previous to this patch, it was not necessary for Mesa to explicitly
invalidate the address-based cache, because there were no reasonable
use cases in which the GPU would write to a vertex data buffer during
a batch, and inter-batch flushing was taken care of by the kernel.

However, with transform feedback, there is now a reasonable use case:
vertex data is written to a buffer using transform feedback, and then
that data is immediately re-used as vertex input in the next drawing
operation.  To make this use case work, we need to flush the
address-based VF cache between transform feedback and the next draw
operation.  Since we are already calling
intel_batchbuffer_emit_mi_flush() when transform feedback completes,
and intel_batchbuffer_emit_mi_flush() is intended to invalidate all
caches, it seems reasonable to add VF cache invalidation to this
function.

As with commit 63cf7fad13fc9cfdd2ae7b031426f79107000300 (i965: Flush
pipeline on EndTransformFeedback), this is not an ideal solution.  It
would be preferable to only invalidate the VF cache if the next draw
call was about to consume data generated by a previous draw call in
the same batch.  However, since we don't have the necessary dependency
tracking infrastructure to figure that out right now, we have to
overzealously invalidate the cache.

Since vertex input is consumed at an earlier pipeline stage than

i965 gen6+: Make intel_batchbuffer_emit_mi_flush() actually flush.

Previous to this patch, the function intel_batchbuffer_emit_mi_flush()
was a bit of a misnomer.  On Gen4+, when not using the blit engine, it
didn't actually flush the pipeline--it simply generated a PIPE_CONTROL
command with the necessary bits set to flush GPU caches.  This was
usually sufficient, since in most situations where
intel_batchbuffer_emit_mi_flush() was called, all we really care about
was ensuring cache coherency.

However, with the advent of OpenGL 3.0, there are two cases in which
data output by one stage of the pipeline might be consumed, in a later
draw operation, by an earlier stage of the pipeline:

(a) When using textures in the vertex shader.

(b) When using drawing with a vertex buffer that was previously
    generated using transform feedback.

This patch addresses case (a) by changing
intel_batchbuffer_emit_mi_flush() so that on Gen6+, it sets the
PIPE_CONTROL_CS_STALL bit (this forces the pipeline to actually
flush).  (Case (b) will be addressed by the next patch in the series).

This is not an ideal solution--in a perfect world, the driver would
have some buffer dependency tracking so that we would only have to
flush the pipeline in the two cases above.  Until that dependency
tracking is implemented, however, it seems prudent to have
intel_batchbuffer_emit_mi_flush() actually flush the pipeline, so that
we get correct rendering, at the expense of a (hopefully small)
performance hit.

The change is only applied to Gen6+, since at the moment only Gen6+
supports the OpenGL 3.0 features that make a full pipeline flush
necessary.

This consists of several related pieces of functionality:

(1) In gen6_sol.c, we set up binding table entries for use by
transform feedback.  We use one binding table entry per transform
feedback varying (this allows us to avoid doing pointer arithmetic in
the shader, since we can set up the binding table entries with the
appropriate offsets and surface pitches to place each varying at the
correct address).

(2) In brw_context.c, we advertise the hardware capabilities, which
are as follows:

   MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS 64
   MAX_TRANSFORM_FEEDBACK_SEPARATE_ATTRIBS        4
   MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS    16

OpenGL 3.0 requires these values to be at least 64, 4, and 4,
respectively.  The reason we advertise a larger value than required
for MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS is that we have already
set aside 64 binding table entries, so we might as well make them all
available in both separate attribs and interleaved modes.

(3) We set aside a single SVBI ("streamed vertex buffer index") for
use by transform feedback.  The hardware supports four independent
SVBI's, but we only need one, since vertices are added to all
transform feedback buffers at the same rate.  Note: at the moment this
index is reset to 0 only when the driver is initialized.  It needs to
be reset to 0 whenever BeginTransformFeedback() is called, and
otherwise preserved.

(4) In brw_gs_emit.c and brw_gs.c, we modify the geometry shader
program to output transform feedback data as a side effect.

(5) In gen6_gs_state.c, we configure the geometry shader stage to
handle the SVBI pointer correctly.

Note: ordering of vertices is not yet correct for triangle strips
(alternate triangles are improperly oriented).  This will be addressed
in a future patch.

mesa: Record transform feedback strides/offsets in linker output.

This patch adds two new fields to the gl_transform_feedback_info
struct:

- BufferStride records the total number of components (per vertex)
  that transform feedback is being instructed to store in each buffer.

- Outputs[i].DstOffset records the offset within the interleaved
  structure of each transform feedback output.

These values are needed by the i965 gen6 and r600g back-ends, so it
seems better to have the linker provide them rather than force each
back-end to compute them independently.

Also, DstOffset helps pave the way for supporting
ARB_transform_feedback3, which allows the transform feedback output to
contain holes between attributes by specifying
gl_SkipComponents{1,2,3,4} as the varying name.
