With the introduction of the pipe_loader_sw_probe_dri helper we
require the sw/dri winsys during linking stage despite it being
unused by any of the targets. This will cause a minor increase
in the resulting library which will be cleaned up via linker
options with upcoming patches.
v2: Link with libswdri.la only when available.

The above function implies using the the xlib winsys, which
has additional library dependencies that should not be forced.
Make the software xlib pipe loader optional thus avoid all
the dependency hell. A user that wishes to use the particular
pipe-loader would need to set the following within configure.ac.
enable_gallium_xlib_loader=yes
v2:
- Wrap sw/xlib/xlib_sw_winsys.h to handle compilation on systems
lacking X11 headers. Spotted by Christian Prochaska.

The blitter is completely ignorant of MSAA buffer layouts, so any
attempt to use BLT paths with MSAA buffers is likely to break
spectacularly.
In most cases, BLORP handles MSAA blits, so we never hit this bug.
Until recently, it also wasn't worth fixing, since Meta couldn't handle
MSAA either, so there was nothing to fall back to. But now there is.
+143 piglit tests on Broadwell (which doesn't have BLORP support).
Surprisingly, three also start failing. Since non-IMS MSAA buffers
store samples in successive array slices, using the blitter ought to
access sample 0 and ignore the rest, which is apparently good enough for
a few not-very-picky Piglit tests. Presumably the meta replacement code
is still broken.
No Piglit changes on Ivybridge.
v2: Move the early return to the top of the function (suggested by
Paul).

Using generic shaders caused a measurable fps drop, which was isolated to
use of full precision (vs half precision) output. This is an attempt to
regain that lost performance by using half precision solid/blit shaders
(when the output format is not float32).
Note: for the built-in shaders, I would not expect them to be register
starved. And in fact it is the solid frag shader that seems to have the
biggest impact. So I suspect you get double the pixel pipe units (or
half the cycles) when the output is half precision. So there may be
some gain to using half precision output for application shaders as
well, even though the rest of register usage is still full precision.
But for half precision to work for more complex shaders, we need to deal
with some constraints, like cat2 needing same precision for it's two src
registers. So for now it is not enabled by default except for the
built-in shaders.

Start putting in place infrastructure to deal with multiple shader
variants. Initially we'll use this for two sided color (frag) and
binning pass (vert) shaders. Possibly need for others later (such
as YUV vs RGB eglImage?).

Easier than making more extensive use of rpt, and the more compact
shaders seem to bring some bit of performance boost. (Perhaps repeat
flag benefits are more than just instruction cache, possibly it saves
on instruction decode as well?)

Instead in the common code, construct these shaders from TGSI. For now
we let a2xx keep it's hand coded shaders, as it's compiler isn't quite
up to the job yet. All the same it is a net drop in code size and gets
rid of special cases.

Make things configurable, and tweak the API a bit to avoid an extra
tgsi_shader_scan(). Getting closer to something generic which can be
moved out of freedreno and shaderd by other drivers.

While we want to be able to print to stdout for glsl_compiler, for
debugging drivers we want to be able to dump to stderr because that's
where other driver debug (like LIBGL_DEBUG) tends to go, and because some

Unfortunately there's only one RT_ARRAY_MODE setting for all
attachments, so clears were previously truncated to the minimum number
of layers any attachment had. Instead set the RT_ARRAY_MODE to 512 (the
max number of layers) before doing the clear. This fixes
gl-3.2-layered-rendering-clear-color-mismatched-layer-count.
Also fix clears of individual layered rt/zeta, in case it ever happens.

Use tex->bo_format instead of zs->format in ilo_blitter_rectlist_clear_zs()
because the latter may be combined depth/stencil format. hiz_can_clear_zs()
is no-op for GEN7+, but move the GEN check so that the assertions are tested.
Finally, call the fast depth clear function from ilo_clear().
