Accumulated changes for various renames and additions, including Gen8
definitions. Some of the dynamic state __SIZE no longer means the size of an
element, but the size of an array of elements. The changes can be seen in
ilo_render_dynamic.c.
LINTERP is implemented as a PLN instruction or a LINE+MAC. PLN and MAC
can do conditional mod. CINTERP is just a MOV.

And unfortunately other shaders do the same thing but with >=/<= which
we can't apply this optimization to because of NaNs.

Looking at one of these examples (tesseract), it's from vec4 load_consts
for a MRT solid fill, which do get CSEed now that we don't memcmp off the
end of the const value and into the SSA def. For the 1-component loads
that are common in i965, we were only memcmping off into the rest of the
usually zero-filled const_value.

Lots of shaders divide by exp2(...) which we turn into a multiplication
by the reciprocal. We can avoid the reciprocal by simply negating exp2's
argument.

It hurts some programs because we make no attempts in the vec4 backend
to avoid MADs if they have constant (or vector uniform) arguments.

Skylake+ doesn't support setting a depth buffer to a 1D surface but it
does allow pretending it's a 2D texture with a height of 1 instead.
This fixes the GL_DEPTH_COMPONENT_* tests of the copyteximage piglit
test (and also seems to avoid a subsequent GPU hang).

Null surfaces are going to be useful to have something to point
unbound image units to, as the ARB_shader_image_load_store extension
requires us to behave deterministically in cases where some shader
tries to access an unbound image unit: Invalid stores and atomics are
supposed to be discarded and invalid loads are supposed to return
zero, which is precisely what the null surface does.

It doesn't really improve locality of texture fetches, quite the
opposite it's a waste of memory bandwidth and space due to tile
alignment.
v2: Check mt->logical_height0 instead of mt->target (Ken). Add short
comment explaining why they shouldn't be tiled.

Negation of UD/UW sources behaves the same as for D/W sources, taking
the two's complement of the source, except for bitwise logical
operations on Gen8 and up which take the one's complement. Fixes
crash in a GLSL shader with subtraction of two unsigned values.
