The DDX may allocate a buffer with a too small size.
Instead of failing, let's pretend everything's alright.
Such bugs should be fixed in the DDX, of course.
NOTE: This is a candidate for the stable branches.
Scalar instruction that need to write to the xyz components of a
register must reserve the RGB instruction slot for a REPL_ALPHA
instruction. With this commit, the scheduler will attempt to free
the RGB slot by moving the write to the w component of a register.
The texture semaphore allows for prefetching of texture data. On my
RV515, this increases the FPS of Lightsmark by 33% (This is with the
reg_rename pass enabled, which is enabled in the next commit).
There is a new env variable now called RADEON_TEX_GROUP, which allows
you to specify the maximum number of texture lookups to do at once.
The default is 8, but different values could produce better results
for various application / card combinations.
We no longer emit full instructions immediately after they have been
merged. Instead merged instructions are added to the ready list and
the scheduler can commit them whenever it wants.
This adds support to the clear and tile caches for integer storage
and clearing, avoiding any floating paths.

these are never USCALED, always UINT in reality.

v2: fixup formatting of table + tabs

now that we have integer texture types I can drop this workaround so that
copies of values is done properly (as floats would fail on some corner cases).

If there is not enough space in pushbuffer for fence emission
(nouveau_fence_emit -> nv50_screen_fence_emit -> MARK_RING),
the pushbuffer is flushed, which through flush_notify ->
nv50_default_flush_notify -> nouveau_fence_update marks currently
emitting fence as flushed. But actual emission is done after this mark.
So later when there is a need to wait on this fence and pushbuffer
was not flushed in between, fence wait will never finish causing
application to hang.
To fix this, introduce new fence state between AVAILABLE and EMITTED,
set it before emission and handle it everywhere.
Additionally obtain fence sequence numbers after possible flush in
MARK_RING, because we want to emit fences in correct order.

We need add a new set of fragment shader variants, along with new vertex
elements for signed and unsigned clears.
The new fragment shader variants are due to the integers values requiring
CONSTANT interpolation. The new vertex element descriptions are for passing
the clear color as an unsigned or signed integer value.

This add support for unsigned/signed integer types via adding a 'pure' bit
in the format description table. It adds 4 new u_format get/put hooks,
for get/put uint and get/put sint so that accessors can get native access
to the integer bits. This is used to avoid precision loss via float converting
paths.
It doesn't add any float fetchers for these types at the moment, GL doesn't
require float fetching from these types and I expect we'll introduce a lot
of hidden bugs if we start allowing such conversions without an API mandating
it.
It adds all formats from EXT_texture_integer and EXT_texture_rg.
0 regressions on llvmpipe here with this.
(there is some more follow on code in my gallium-int-work branch, bringing
softpipe and mesa to a pretty integer clean state)
