r600/sb: Fix loop optimization related hangs on eg
Make sure unused ops and their references are removed, prior to entering
the GCM (global code motion) pass, to stop GCM from breaking the loop
logic and thus hanging the GPU.
Turns out, that sb has problems with loops and node optimizations
regarding associative folding:
- the global code motion (gcm) pass moves ops up a loop level/basic block
until they've fulfilled their total usage count
- if there are ops folded into others, the usage count won't be
fulfilled and thus the op moved way up to the top
- within GCM the op would be visited and their deps would be moved
alongside it, to fulfill the src constaints
- in a loop, an unused op is moved out of the loop and GCM would move
the src value ops up as well
- now here arises the problem: if the loop counter is one of the src
values it would get moved up as well, the loop break condition would
never get hit and the shader turn into an endless loop, resulting in the
GPU hanging and being reset
A reduced (albeit nonsense) piglit example would be:
[require]
GLSL >= 1.20
[fragment shader]
uniform int SIZE;
uniform vec4 lights[512];
void main()
{
float x = 0;
for(int i = 0; i < SIZE; i++)
x += lights[2*i+1].x;
}
[test]
uniform int SIZE 1
draw rect -1 -1 2 2
Which gets optimized to:

editorconfig: Fix up the tab rendering width.
Our editorconfig file looked sensible, saying that we wanted to indent
with spaces and use 3/4/whatever space indentation. However, the spec has
this little surprise:
"tab_width: a whole number defining the number of columns used to
represent a tab character. This defaults to the value of indent_size
and doesn't usually need to be specified."
so once my editor started respecting editorconfig, the files that have
tabs left in them started getting rendered wrong, showing up like this in
brw_program.c:
case GL_COMPUTE_PROGRAM_NV: {
struct brw_program *prog = rzalloc(NULL, struct brw_program);

meta: Disable dithering during glGenerateMipmap
Fixes tests 'dEQP-GLES3.functional.texture.mipmap.*.generate.rgba5551*' on
Intel Broadwell 0x1616.
The GL 4.5 spec describes the algorithm of glGenerateMipmap as:
The contents of the derived images are computed by repeated, filtered
reduction of the level base image. [...] No particular filter algorithm is
required, though a box filter is recommended as the default filter.
Consider a texture for which all pixels are identical at level 0.
From the spec's description above, one may reasonably assume that the "filtered
reduction" of level 0 produces a new miplevel for which again all pixels are
identical. For any 2x2 subspan of identical pixels, it is difficult to see how
the "filtered reduction" of that subspan can produce a pixel that differs from
the source pixels.
Dithering during _mesa_meta_GenerateMipmap() violated that reasonable
assumption.

i965: Remove perf monitor/query backend
In its current state the unified i965 backend for
AMD_performance_monitor and INTEL_performance_query isn't able to report
meaningful Observation Architecture metrics since we haven't so far had
the necessary kernel support to fully configure the OA unit, nor the
corresponding support for normalizing the counters into a form that can
be usefully interpreted by application developers (as opposed to raw
values that may, for example, scale by the number of EUs there are).
So that we can focus on implementing just one of these extensions fully
and since we anticipate some significant backend changes as we look to
use a new kernel interface to configure the OA unit, this patch removes
the current backend. This will simplify our ability to update the
frontend infrastructure and backend interface before updating our
support for performance counters.

i965/vec4: prevent spilling of DOUBLE_TO_SINGLE destination
FROM_DOUBLE opcodes are setup so that they use a dst register
with a size of 2 even if they only produce a single-precison
result (this is so that the opcode can use the larger register to
produce a 64-bit aligned intermediary result as required by the
hardware during the conversion process). This creates a problem for
spilling though, because when we attempt to emit a spill for the
dst we see a 32-bit destination and emit a scratch write that
allocates a single spill register, making the intermediary writes
go beyond the size of the allocation.
Prevent this by avoiding to spill the destination register of these
opcodes.
Alternatively, we can avoid this by splitting the opcode in two: one
that produces a 64-bit aligned result and one that takes the 64-bit
aligned result as input and produces a 32-bit result from it.

i965/vec4: avoid spilling of registers that mix 32-bit and 64-bit access
When 64-bit registers are (un)spilled, we need to execute data shuffling
code before writing to or after reading from memory. If we have instructions
that operate on 64-bit data via 32-bit instructions, (un)spills for the
register produced by 32-bit instructions will not do data shuffling at all
(because we only see a normal 32-bit istruction seemingly operating on
32-bit data). This means that subsequent reads with that register using DF
access will unshuffle data read from memory that was never adequately
shuffled when it was written.
Fixing this would require to identify which 32-bit instructions write
64-bit data and emit spill instructions only when the full 64-bit
data has been written (by multiple 32-bit instructions writing to different
offsets of the same register) and always emit 64-bit unspills whenever
64-bit data is read, even when the instruction uses a 32-bit type to read
from them.

The current spilling code can't spill vgrf allocations larger than 1

is handled properly for DF data types by emitting 2 scratch messages and
doing data shuffling). We accomplish this by not auto-disabling spilling
for vgrf allocations with a size of 2, and then disable spilling on any
register with an offset != 0B (which indicates array access).
Disable spilling of partial DF reads/writes because these don't read/write
data for both logical threads and our scratch messages for 64-bit data
need data for both threads to be present.

This also fixes ZW writes from X/Y channels like in:

Because DF regions use 2-wide rows with a vstride of 2, the region generated

we end up writing r0.z in r2.z instead of r0.x. Using a vertical stride of 0
