Avoid deferring building shaders until draw time, should hopefully
reduce any stuttering, as well as enable shader-db style analysis.

Unfortunately flatshading is an all-or-nothing proposition on nvc0,
while GL 3.0 calls for the ability to selectively specify explicit
interpolation parameters on gl_Color/gl_SecondaryColor which would
override the flatshading setting. This allows us to fix up the
interpolation settings after shader generation based on rasterizer
settings.
While we're at it, we can add support for dynamically forcing all
(non-flat) shader inputs to be interpolated per-sample, which allows
st/mesa to not generate variants for these.
Fixes the remaining failing glsl-1.30/execution/interpolation piglits.

nir_intrinsic_load_patch_vertices_in corresponds to gl_PatchVerticesIn,
a special input in both the TCS and TES stages.
nir_intrinsic_load_tess_coord corresponds to gl_TessCoord, a special
tessellation evaluation shader input.
nir_intrinsic_load_tess_level_outer/inner correspond to the
gl_TessLevelOuter[] and gl_TessLevelInner[] evaluation shader inputs,
which we treat as system values because they're stored specially.
(These intrinsics are only for the TES - the TCS uses output variables.)

Consider the case of two nearly identical GLSL fragment shaders:
out vec4 color;
void main() { color = vec4(1); }
and
layout(early_fragment_tests) in;
out vec4 color;
void main() { color = vec4(1); }
These shaders compile to the exact same assembly, but have distinct
values for brw_wm_prog_data::early_fragment_tests.
Since these are two independent GLSL shaders, they have different
program keys - notably, brw_wm_prog_key::program_string_id differs.
When uploading the second, brw_upload_cache will find an existing copy
of the assembly in the cache BO, which means matching_data will be
non-NULL. Although we create a second cache item (with the new key
and prog_data), we set item->offset to the existing copy and avoid
re-uploading duplicate assembly.
However, brw_search_cache() would only flag BRW_NEW_*_PROG_DATA if
item->offset differed from the supplied offset. With reuse, both
programs have the same offset, but prog_data changed. We have to
flag it, but failed to.
To fix this, we simply need to check if the aux (prog_data) pointer
changed. If either the assembly or the prog_data differs, flag it.
This fixes a regression since 1bba29ed40,
where Topi fixed brw_upload_cache() to actually reuse identical
assembly. Prior to that, reuse basically never happened due to bugs.
Unfortunately, this code apparently wasn't prepared to handle reuse!

With just the right sequence of per-vertex commands and state changes,
it's possible for this assertion to fail (such as with viewperf11's
lightwave-06-1 test). Instead of asserting, return 0 so that the
caller knows the VBO is full and needs to be flushed.

There is only one function that can be called, which is well known at

The abstraction used here seems unnecessary, so let's use a direct call
to brw_stage_prog_data_free() when appropriate, cut down the size of

The maximum number of active variables for shader storage blocks should
take into account the specific rules for shader storage blocks, i.e. for

will be generated only for the first array element, regardless of its type.

This paves the way for copy propagating our unpacks. We end up with a
small change on shader-db:
total instructions in shared programs: 89390 -> 89251 (-0.16%)
instructions in affected programs: 19041 -> 18902 (-0.73%)
which appears to be because we no longer convert MOVs for an FMAX dst,
r4.unpack, r4.unpack (instead of the previous MOV dst, r4.unpack), and
this ends up with a slightly better schedule.
At one point I thought packs and unpacks were in the same field of the
instruction. They aren't. These instructions therefore never cause a
pack.
total instructions in shared programs: 89472 -> 89390 (-0.09%)
instructions in affected programs: 15261 -> 15179 (-0.54%)
When a TCS is present, the TES input gl_PatchVerticesIn is actually a
constant - it's simply the # of output vertices specified by the TCS
layout qualifiers. So, we can replace the system value with a constant,
which may allow further optimization, and will likely be more efficient.
If the TCS is absent, we can't do this optimization.
