i965: Rename INTEL_DEBUG=vec4vs to INTEL_DEBUG=vec4.
driParseDebugString() doesn't have actual code to parse comma separated
lists (or any other supported options?); instead it dumbly uses strstr().
This means that INTEL_DEBUG="vec4vs" will trigger both DEBUG_VEC4VS and
DEBUG_VS, as "vs" is also a substring.
We should probably improve the driconf parsing, but for now, just rename
the option so it's usable in the meantime.

i965: change the meaning of cpp for compressed textures
An ASTC block takes up 16 bytes for all block width and height configurations.
This size is not integrally divisible by all ASTC block widths. Therefore cpp
is changed to mean bytes per block if the texture is compressed.
Because the original definition was bytes per block divided by block width, all
references to the mipmap width must be divided the block width. This keeps the
address calculation formulas consistent. For example, the units for miptree_level
x_offset and miptree total_width has changed from pixels to blocks.

If that happens, all shaders, context states, bound resources, draw
parameters, and driver debug information (if any) will be dumped into:

Note that the context is flushed after every draw/clear/copy/blit operation
and then waited for to find the exact call that hangs.
You can also do:
GALLIUM_DDEBUG=always
to do the dumping after every draw/clear/copy/blit operation without
flushing and waiting.
Examples of driver states that can be dumped are:
- Hardware status registers saying which hw block is busy (hung).

This is mathematically equivalent, but uses some tricks to avoid

performance doubling or so. As a side note, some quick tests show that
llvm's loop vectorizer would be able to properly vectorize this version

This drops some of the more expensive float operations, in particular
- int-cast floors (pointless, values always positive)
- 2 raised to (signed) integers (replace with simple exponent manipulation),
getting rid of a misguided comment in the process (implement with table...)
- float division (replace with mul of reverse of those exponents)
This is like 3 times faster (measured for float3_to_rgb9e5), though it depends

Previously, there were four type_size() functions in play - the i965
compiler backend defined scalar and vec4 type_size() functions, and
nir_lower_io contained its own similar functions.
In fact, the i965 driver used nir_lower_io() and then looped over the

two are /basically/ the same, but not exactly in obscure cases like
subroutines and images.

Revert "radeon/winsys: increase the IB size for VM"
This reverts commit

It regressed performance. It looks like smaller IBs are better, because
the GPU goes idle quicker and there is less waiting for buffers and fences.
