When a buffer object is bound to one of the indexed uniform buffer
binding points, assume that from that point on it may be used as
a uniform buffer.

In the drivers, we occasionally want to reallocate the backing
store for a buffer object; often to avoid waiting for the GPU
to be finished with the previous contents.
At the point that happens, we don't have a good way of determining
where else the buffer object may be bound, and so no good way of
determining which dirty flags need to be raised -- it's fairly
expensive to go looking at all the possible binding points.
Until now, we've considered any BO to be possibly bound as a UBO or
TexBO, and flagged all that state to be reemitted.
Instead, remember what kinds of binding point this buffer has ever
been used with, so that the drivers can flag only what they need.
I don't expect these bits to ever be reset, but that doesn't matter
for reasonable apps.

Before, we had 3 different emit functions for various different gen's,
as well as some ancilliary work that was the same across all gen's which
was either contained in functions or duplicated across the GLSL IR and
Mesa IR backends. Now, we have a single method, emit_texture(), that
takes all the information needed to make a texture instruction and
handles all the setup, and all we have to do to emit a texture
instruction while converting from GLSL IR, Mesa IR, or any new backend
is to extract the information emit_texture() needs and then call it.

Because we reuse various bits of emit code (for state/vertex/prog/etc)
for both regular draws and internal draws (gmem<->mem, clear, etc), the
number of parameters getting passed around has been growing. Refactor
to group these into fd3_emit. This simplifies fxn signatures, avoids
passing around shader key on the stack, etc. It also gives us a nice
place to cache shader-variant lookup to avoid looking up shader variants
multiple times per draw (without having to *also* pass them around as
fxn args everywhere).

Get rid of fd3_vertex_buf and use fd_vertex_state directly for all
draws. Removes a tiny bit of CPU overhead for munging around the vertex
state every time it is emitted, but more importantly it cleans things up
for later optimizations, so the emit paths don't have to special case
internal draws (gmem<->mem, clears, etc) with regular draws.
Instead of constructing fd3_vertex_buf array each time for internal
draws, and context init time pre-create solid_vbuf_state and
blit_vbuf_state.

Due to the implicit move-from-GRF, unary math looks a lot like the Gen6+
math instruction: it's a single instruction (SEND) with a GRF source.
The difference is that it also implicitly clobbers a message register.
The only visible effect is that CSE will remove the MRF-clobbering from
later math operations. This should be fine; compute_to_mrf and
remove_redundant_mrf_writes don't look at the values populated by
implied writes, so they can't rely on those values being present.
Less interference may actually help those passes make more progress.
Binary math is still problematic, since it involves a separate MOV
instruction to load the second operand. We continue disallowing CSE for
binary math operations.
