i965: Don't grow batch/state buffer on every emit after an overflow.

Once we reach the intended size of the buffer (BATCH_SZ or STATE_SZ), we
try and flush.  If we're not allowed to flush, we resort to growing the
buffer so that there's space for the data we need to emit.

We accidentally got the threshold wrong.  The first non-wrappable call
beyond (e.g.) STATE_SZ would grow the buffer to floor(1.5 * STATE_SZ),
The next call would see we were beyond STATE_SZ and think we needed to
grow a second time - when the buffer was already large enough.

We still want to flush when we hit STATE_SZ, but for growing, we should
use the actual size of the buffer as the threshold.  This way, we only
grow when actually necessary.

i965: Use old_bo->align when growing batch/state buffer instead of 4096.

The intention here is make the new BO use the same alignment as the old
BO.  This isn't strictly necessary, but we would have to update the
'alignment' field in the validation list when swapping it out, and we
don't bother today.

The batch and state buffers use an alignment of 4096, so this should be
equivalent - it's just clearer than cut and pasting a magic constant.

i965: Program the dynamic state heap size to MAX_STATE_SIZE.

STATE_BASE_ADDRESS specifies a maximum size of the dynamic state
section, beyond which data supposedly reads back as 0.  On Gen8+,
we were programming it to the size of the buffer.  This worked fine
until we started growing the state buffer in commit 2dfc119f22f25708.
When the state buffer grows, the value in STATE_BASE_ADDRESS becomes
too small, and our state beyond STATE_SZ bytes would read back as 0.

To avoid having to update the value, we program it to MAX_STATE_SIZE.
We used to program the upper bound to the maximum on older hardware
anyway, so programming it too large isn't a big deal.

Bogus SURFACE_STATE can easily lead to GPU hangs and misrendering.
DiRT Rally was hitting the statebuffer growth path, and suffered from
bad texture corruption and GPU hangs (usually around the same time).

This patch fixes both issues.

mesa: deal with vs_inputs as 64-bit unsigned integer

Commit 78942e ("mesa: shrink VERT_ATTRIB bitfields to 32 bits") uses
vs_prog_data->vs_inputs as if it were a 32-bit unsigned integer.

But actually it is a 64-bit integer, and as such it is used in other
parts of Mesa code. It is worth to note that bits from the entire range
are used, and not only 32-bits. This is due our implementation for
handling 64-bit dual-slot input attributes, which requires to use a
larger bitfield to manage them.

mesa/gles: adjust internal format in glTexSubImage2D error checks

When floating point textures are created on OpenGL ES 2.0, driver

adjust_for_oes_float_texture. Error checking for glTexImage2D properly
checks that sized formats are not used. We use same error checking
path for glTexSubImage2D (since there is lot of overlap), however since

intel/blorp: Add fast-clear to the special case in MSAA resolves

This doesn't go all the way of avoiding the txf_ms if it's fast-cleared,
however it does at least make us only do it once.  This should improve
performance of MSAA resolves in the presence of lots of clear color.
Without the patch, enabling fast-clears in the multisampling Sascha demo
drops the framerate by about 10%.  With this patch, enabling fast-clears
increases the demo's framerate by 25%.

st/glsl_to_tgsi: make use of driver_cache_blob with the disk cache

driver_cache_blob was introduced with the i965 disk cache, it allows
us to simplify the cache a little and possibly offers some minor
speed improvements since we load the GLSL metadata and TGSI from

Using driver_cache_blob should also make it straight forward to
