This way we correctly report "Too many temporaries" errors.

Note: This is a candidate for the stable branches.

Instruction attributes like WriteALUResult and ALUResultCompare
were being discarded during the some of the local transformations.

This fixes the following piglit tests:

glsl1-inequality (vec2, pass)
loopfunc
fs-any-bvec2-using-if
fs-op-ne-bvec2-bvec2-using-if
fs-op-ne-ivec2-ivec2-using-if
fs-op-ne-mat2-mat2-using-if
fs-op-ne-vec2-vec2-using-if
fs-op-ne-mat2x3-mat2x3-using-if
fs-op-ne-mat2x4-mat2x4-using-if

https://bugs.freedesktop.org/show_bug.cgi?id=45921

NOTE: This is a candidate for the stable branches.

The loop registers weren't being cleared, so any shader that was
executed after a shader containing loops was at risk of having a loop
randomly inserted into it.

This fixes over one hundred piglit tests, although these test
only failed during full piglit runs and would pass if
run individually.  The exact number of piglit tests that this patch
fixes will vary depending on the version of piglit and the order the
tests are run.

NOTE: This is a candidate for the stable branches.

Though I don't think we'll ever expose > 1.

The shader transformation code sometimes produced invalid TGSI.

RET in the main function doesn't work. This should be fixed in Draw, but meh.

Draw can do it just fine.

This reverts commit 0950086376.

It was decided to refactor the transfer API instead of adding workarounds
to address the performance issues.

On R500 chips, shader instructions can take 7-bit (3-bit mantissa, 4-bit
exponent) floating point values as inputs in place of registers.

r600g is the only driver which has made use of it. The reason the CAP was
added was to fix some piglit tests when the GLSL pass lower_output_reads
didn't exist.

However, not removing output reads breaks the fallback for glClampColorARB,
which assumes outputs are not readable. The fix would be non-trivial
and my personal preference is to remove the CAP, considering that reading
outputs is uncommon and that we can now use lower_output_reads to fix
the issue that the CAP was supposed to workaround in the first place.

v2:
  - s/$(top_builddir)/$(top_srcdir)/
  - Always generate Makefile.in

v3:
  - Fixes from Matt Turner
  - Use Mesa CFLAGS

KILP instruction inside IF blocks were being lowered to an unconditional
KIL.  Since r300 doesn't support branching, when the IF's were lowered
to conditional moves, the KIL would always be executed.  This is not a
problem with the mesa state tracker, because the GLSL compiler handles
lowering IF's, but this bug was appearing in the VDPAU state tracker,
which does not use the GLSL compiler.

Note: This is a candidate for the stable branches.

A winsys is already a private object of a driver.

Just to be safe.

And reset the dest pointer to NULL after it.

Just let the hardware do it if it can and avoid drivers having to
check for the special case on each draw call.

v2: update the draw module

As they now indirectly include on libdrm/radeon_surface.h.

Tiled surface have all kind of alignment constraint that needs to
be met. Instead of having all this code duplicated btw ddx and
mesa use common code in libdrm_radeon this also ensure that both
ddx and mesa compute those alignment in the same way.

v2 fix evergreen
v3 fix compressed texture and workaround cube texture issue by
   disabling 2D array mode for cubemap (need to check if r7xx and
   newer are also affected by the issue)
v4 fix texture array
v5 fix evergreen and newer, split surface values computation from
   mipmap tree generation so that we can get them directly from the
   ddx
v6 final fix to evergreen tile split value
v7 fix mipmap offset to avoid to use random value, use color view
   depth view to address different layer as hardware is doing some
   magic rotation depending on the layer
v8 fix COLOR_VIEW on r6xx for linear array mode, use COLOR_VIEW on
   evergreen, align bytes per pixel to a multiple of a dword
v9 fix handling of stencil on evergreen, half fix for compressed
   texture
v10 fix evergreen compressed texture proper support for stencil
    tile split. Fix stencil issue when array mode was clear by
    the kernel, always program stencil bo. On evergreen depth
    buffer bo need to be big enough to hold depth buffer + stencil
    buffer as even with stencil disabled things get written there.
v11 rebase on top of mesa, fix pitch issue with 1d surface on evergreen,
    old ddx overestimate those. Fix linear case when pitch*height < 64.
    Fix r300g.
v12 Fix linear case when pitch*height < 64 for old path, adapt to
    libdrm API change
v13 add libdrm check

v2: handle the cap in r300 and r600 as well

Additional info for r600g:
   The env var R600_GLSL130=1 enables GLSL 1.3.
   Along with R600_STREAMOUT=1, it enables full GL 3.

For ARB_color_buffer_float. Most hardware can't do it and st/mesa is
the perfect place for a fallback.
The exceptions are:
- r500 (vertex clamp only)
- nv50 (both)
- nvc0 (both)
- softpipe (both)

We also have to take into account that r300 can do CLAMPED vertex colors only,
while r600 can do UNCLAMPED vertex colors only. The difference can be expressed
with the two new CAPs.

This fixes a memory leak on i965 context destruction.

NOTE: This is a candidate for the 8.0 branch.

Create the video buffers in the format the driver preffers.
This temporary creates problems with decoder less VDPAU video playback.

Also move the code structure at the beginning of r300_fragment_shader_code
to detect underflows easily with valgrind.
