Apparently guardband clipping doesn't work like we thought: objects
entirely outside fthe guardband are trivially rejected, regardless of
their relation to the viewport. Normally, the guardband is larger than
the viewport, so this is not a problem. However, when the viewport is
larger than the guardband, this means that we would discard primitives
which were wholly outside of the guardband, but still visible.
We always program the guardband to 8K x 8K to enforce the restriction
that the screenspace bounding box of a single triangle must be no more
than 8K x 8K. So, if the viewport is larger than that, we need to
disable guardband clipping.

Now that we have the data available, we need to expose it to the
shaders. We can reuse the same vertex element that we use for
gl_VertexID, but we need to back it by an actual vertex buffer.
A hardware restriction requires that vertex attributes coming from a
buffer (STORE_SRC) must come before any other types (i.e. STORE_0).
So, we have to make gl_BaseVertex be the .x component of the vertex
attribute. This means moving gl_VertexID to a different component.
I chose to move gl_VertexID and gl_InstanceID to the .z and .w
components, respectively, to make room for gl_BaseInstance in the .y
component (which would also come from a buffer, and therefore be
STORE_SRC).

The lower_vertex_id pass converts uses of the gl_VertexID system value

This doesn't quite make depth-tex-compare work, presumably because we're
not hitting equality with itof(sample) * 1.0/0xffffff in the 0xffffff
case. arb_fragment_program_shadow tests pass, though, as well as a bunch
of other shadow-related stuff.
We potentially need to be careful that use of a value stored in r4 isn't
copy-propagated (or something) across another r4 write. That doesn't
appear to happen currently, and this makes the dataflow more obvious. It
also opens up not unpacking the r4 value, which will be useful for depth
textures.
Since software primitive-restart emulation is going to be removed (and
anyways, mostly seemed to be crash prone in combination with
u_primconvert and oddball scenarios (like PIPE_PRIM_POLYGON with only a
single vertex), might as well do it in hardware (which fortunately
didn't turn out to be too hard to figure out).

We currently aren't too clever about dealing with running out of
cmdstream buffer space. Since we use a single buffer for both drawing
and tiling commands, we need to ensure there is enough space at the tail
of the cmdstream buffer to fit the tiling commands.
Until we get more clever, the easy solution is a threshold to trigger
flushing rendering even if the application does not trigger flush (swap,
changing render target, etc). This way we at least don't crash for apps
that do several thousand draw calls (like some piglit tests do).

Most of the things the new compiler still has trouble with basically
amount to cp stage removing too many copies. But without the cp stage,
the shaders the new compiler produces are still better (perf and
correctness) than the old compiler. So a simple thing to do until I
have more time to work on it is first trying falling back to new
compiler without cp, before finally falling back to old compiler.

Excess conversions considered harmful.
Recently Matt reworked the boolean uniform handling to use the value of
UniformBooleanTrue, rather than integer 1, when uploading uniforms:
mesa: Upload boolean uniforms using UniformBooleanTrue.
glsl: Use UniformBooleanTrue value for uniform initializers.
Marek then set the default to 1.0f for drivers without native integer
support:
mesa: set UniformBooleanTrue = 1.0f by default
However, ir_to_mesa was assuming a value of integer 1, and arranging for
it to be converted to 1.0f on upload. Since Marek's commit, we were
uploading 1.0f = 0x3f800000 which was being interpreted as the integer
value 1065353216 and converted to float as 1.06535322E9, which broke
assumptions in ir_to_mesa that "true" was exactly 1.0f.

The rest of stencil handling isn't done yet, but it documents an extra
cl_u8(0) and helps make it obvious why we don't need to format clear_depth
the same way the depth/stencil buffer is formatted.
For now it still requires the color buffer to be present -- we're relying
on the store of color buffer contents to end the frame, and we have to do
something with color buffers in the rendering config packet.
