llvmpipe: decrease MAX_SCENES from 2 to 1
Multiple scenes per context are meant to be used so a new scene can be built
while another one is processed in rasterization. However, quite surprisingly,
this does not actually work (and according to git log, possibly never did,
though maybe it did at some point further back (5 years+) but was buggy)
because we always wait immediately on the rasterizer to finish the scene when
contexts (and hence setup/scene) is flushed. This means when we try to get
an empty scene later, any old one is already empty again.
Thus using multiple scenes is just a waste of memory (not too bad, since the
additional scenes are guaranteed to be empty, which means their size ought to
be one data block (64kB) plus the size of some structs), without actually
really doing anything. (There is also quite some code for the whole concept of
multiple scenes which doesn't really do much in practice, but keep it hoping
the wait-on-scene-flush can be fixed some day.)

draw: use the prim type from prim_info not emit in passthrough emit

draw: use correct output prim for non-adjacent topologies in prim assembler.
The decomposition done in the prim assembler will turn tri fans into tris,
but this wasn't reflected in the output prim type. Meaning with a tri fan
with 6 verts input, the output was a tri fan with 12 vertices instead of a
tri list with 12 vertices (not as bad as it sounds, since the additional tris
created would all be degenerate since they'd all have two times vertex zero
but still bogus).
This is because the prim assembler is used if either the input topology is
something with adjacency, or if prim id needs to be injected, and for the
latter case topologies without adjacency can be converted to basic ones.
Unfortunately decomposition here for inserting prim ids is necessary, at
least for the indexed case where we can't just insert the prim id at the
right place depending on provoking vertex.

BRW_NEW_VERTICES is flagged every time we draw a primitive. Having
the brw_vs_prog atom depend on BRW_NEW_VERTICES meant that we had to
compute the VS program key and do a program cache lookup for every
single primitive. This is painfully expensive.
The workaround bit computation is almost entirely based on the vertex
attribute arrays (brw->vb.inputs[i]), which are set by brw_merge_inputs.
The only thing it uses the VS program for is to see which VS inputs are
actually read. brw_merge_inputs() happens once per primitive, and can
safely look at the currently bound vertex program, as it doesn't change
in the middle of a draw.
This patch moves the workaround bit computation to brw_merge_inputs(),
right after assigning brw->vb.inputs[i], and stores the previous WA bit
values in the context. If they've actually changed from the last draw
(which is uncommon), we signal that we need a new vertex program,
causing brw_vs_prog to compute a new key.

st/nine: sm1_declusage_to_tgsi, do not restrict indices with TGSI_SEMANTIC_GENERIC
With sm3, you can declare an input/output with an usage and an usage index.
Nine code hardcodes the translation usage/index to a corresponding TGSI code.
The translation was limited to a few usage/index combinations that were corresponding
to most of the needs of games, but some games did not work.
This patch rewrites that Nine code to map all possible usage/index combination
to TGSI code. The index associated to TGSI_SEMANTIC_GENERIC doesn't need to be low
for good performance, as the old code was supposing, and is not particularly bounded
(it's UINT16). Given the index is BYTE, we can map all combinations.

i965: Rename CACHE_NEW_*_PROG to BRW_NEW_*_PROG_DATA.
Now that we've moved a bunch of CACHE_NEW_* bits to BRW_NEW_*, the only
ones that are left are legitimately related to the program cache. Yet,
it seems a bit wasteful to have an entire bitfield for only 7 bits.
State upload is one of the hottest paths in the driver. For each atom
in the list, we call check_state() to see if it needs to be emitted.
Currently, this involves comparing three separate bitfields (mesa, brw,
and cache). Consolidating the brw and cache bitfields would save a
small amount of CPU overhead per atom. Broadwell, for example, has
57 state atoms, so this small savings can add up.
CACHE_NEW_*_PROG covers the brw_*_prog_data structures, as well as the
offset into the program cache BO (prog_offset). Since most uses refer
to brw_*_prog_data, I decided to use BRW_NEW_*_PROG_DATA as the name.
Removing "cache" completely is a bit painful, so I decided to do it in
several patches for easier review, and to separate mechanical changes
from manual ones. This one simply renames things, and was made via:
$ for file in *.[ch]; do
sed -i -e 's/CACHE_NEW_\([A-Z_\*]*\)_PROG/BRW_NEW_\1_PROG_DATA/g' \
-e 's/BRW_NEW_WM_PROG_DATA/BRW_NEW_FS_PROG_DATA/g' $file
done
Note that BRW_NEW_*_PROG_DATA is still in .cache, not .brw!
The next patch will remedy this flaw. It will also fix the
alphabetization issues.
