I always thought that the is_control_flow() -> return false check was a
bad hack, and some previous attempts to remove it have failed and have
been reverted.
The previous two patches fix some problems that caused register
coalescing to not notice some interference between registers, which the
is_control_flow() check apparently works around.
With that fixed, we can calculate interference more accurately.

This is like identity or trace, but simpler. It doesn't wrap most states.
Run with:
GALLIUM_DDEBUG=1000 [executable]
where "executable" is the app and "1000" is in miliseconds, meaning that
the context will be considered hung if a fence fails to signal in 1000 ms.
If that happens, all shaders, context states, bound resources, draw
parameters, and driver debug information (if any) will be dumped into:
/home/$username/dd_dumps/$processname_$pid_$index.
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).
- Disassembled shaders in a human-readable form.
- The last submitted command buffer in a human-readable form.

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 code (lifted straight from the extension) was doing things the most

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
(e.g. llvm is clever enough to replace exp2 with ldexp whereas gcc is not,
division is not too bad on cpus with early-exit divs).

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
components using its own type_size - meaning both were in play. The
two are /basically/ the same, but not exactly in obscure cases like
subroutines and images.
This patch removes nir_lower_io's functions, and instead makes the

flexibility in deciding how it wants to count things, reduces code
duplication, and improves consistency.
