The change "mesa/readpix: Don't clip in _mesa_readpixels()" caused a
few piglit regressions. The failing tests use glReadPixels to read
from the front color buffer. The problem is we were trying to read
from a non-existant front color buffer. The front color buffer is
created on demand in st/mesa. Since the missing buffer bounds were
effectively 0 x 0 the glReadPixels was totally clipped and returned
early.
The fix involves creating the real front color buffer when we're about
to try reading from it.
Tested with llvmpipe and VMware driver on Linux, Windows.

The current code in r600_translate_colorswap uses the swizzle information
to determine which colorswap to use.
This works for BE & LE when the nr_channels is <4, but when nr_channels==4
(e.g. PIPE_FORMAT_A8R8G8B8_UNORM), this method can not be used for both BE
and LE, because the swizzle info is the same for both of them.
As a result, r600g doesn't support 24bit color formats, only 16bit, which
forces the user to choose 16bit color in X server.
This patch fixes this bug by separating the checks for LE and BE and
adapting the swizzle conditions in the BE part of the checks.
Tested on an Evergreen GPU (Cedar GL FirePro 2270) running inside POWER7
Big-Endian Machine.

Before the luminance stride was based on the size of GL_FLOAT
which is just the type constant (0x1406). Change it to use the
size of GLfloat.

"st/mesa: overhaul vertex setup for clearing, glDrawPixels, glBitmap"
added a vertex shader declaring IN[0] and IN[2], but not IN[1].
Drivers relying on tgsi_shader_info can't handle holes in declarations,
because tgsi_shader_info doesn't track that.
This is just a quick workaround meant for stable that will work for vertex
shaders.
This fixes radeonsi DrawPixels and CopyPixels crashes.

So the result is of float type if we're implementing the float
overload of imageAtomicExchange. This is the only back-end change
required to support OES_shader_image_atomic AFAICT.

is enabled.
This is basically just the same atomic functions exposed by
ARB_shader_image_load_store, with one exception:
"highp float imageAtomicExchange(
coherent IMAGE_PARAMS,
float data);"
There's no float atomic exchange overload in the original
ARB_shader_image_load_store or GL 4.2, so this seems like new
functionality that requires specific back-end support and a separate
availability condition in the built-in function generator.
v2: Move image availability predicate logic into a separate static
function for clarity. Had to pull out the image_function_flags
enum from the builtin_builder class for that to be possible.

Actually OP_SELP doesn't need to be a compare instruction. Instead we
just need to set the NOT modifier when building the instruction.
While we are at it, fix the dst register type and use a GPR.

Shader stats from VERDE:
Default scheduler:
Totals:
SGPRS: 491272 -> 488672 (-0.53 %)
VGPRS: 289980 -> 311093 (7.28 %)
Code Size: 11091656 -> 11219948 (1.16 %) bytes
LDS: 97 -> 97 (0.00 %) blocks
Scratch: 1732608 -> 2246656 (29.67 %) bytes per wave
Max Waves: 78063 -> 77352 (-0.91 %)
Wait states: 0 -> 0 (0.00 %)
Looking at some of the worst regressions, I get:
- The VGPR increase seems to be caused by the fact that if PS has used less
than 16 VGPRs, now it will always use 16 VGPRs and sometimes even 20.
However, the wave count remains at 10 if VGPRs <= 24, so no harm there.
- The scratch increase seems to be caused by SGPR spilling.
The unnecessary SGPR spilling has been an ongoing issue with the compiler
and it's completely fixable by rematerializing s_loads or reordering
instructions.
SI scheduler:
Totals:
SGPRS: 374848 -> 374576 (-0.07 %)
VGPRS: 284456 -> 307515 (8.11 %)
Code Size: 11433068 -> 11535452 (0.90 %) bytes
LDS: 97 -> 97 (0.00 %) blocks
Scratch: 509952 -> 522240 (2.41 %) bytes per wave
Max Waves: 79456 -> 78217 (-1.56 %)
Wait states: 0 -> 0 (0.00 %)
VGPRs - same story as before. The SI scheduler doesn't spill SGPRs so much
and generally spills way less than the default scheduler.
(522240 spills vs 2246656 spills)
