i915g: fix incorrect gl_FragCoord value

On Intel Pineview M hardware, the i915 gallium driver doesn't output
the correct gl_FragCoord. It seems to always have an X coord of 0.0
and a Y coord of the window's height in pixels, e.g. 600.0f or such.

I believe this is a regression caused in part by this commit:
afa035031ff9e0c07a2297d864e46c76f7bfff58

The old behavior used the output at index zero, while the new behavior
uses actual zeroes. In the case of gl_FragCoord the output at index
zero happened to be the correct one, so the behavior appeared correct
although the code already had a bug.

Fixed by checking for I915_SEMANTIC_POS when setting up texCoords. If
the generic_mapping is I915_SEMANTIC_POS, look for the
TGSI_SEMANTIC_POSITION instead of a TGSI_SEMANTIC_GENERIC output.

st/nine: Fix check and remove useless code in swapchain9

The removed code was there for two reasons:
1) Allow DF16, DF24, INTZ to be used as depth buffer
for swapchain, if the driver doesn't support
PIPE_BIND_SAMPLER_VIEW for the underlying format
2) Set PIPE_BIND_SAMPLER_VIEW if possible, such that
if StretchRect is called on the depth texture, it is happy.

1) The reason these formats needed a workaround is because
the check flags for them in CheckDeviceFormat were incorrect,
which led applications to think the formats were valid for
swapchains, even if they weren't supported.
2) StretchRect limitations for depth buffers force
the resource_copy_region path, which should be fine without
PIPE_BIND_SAMPLER_VIEW.

Thus fix the check for 1), and remove the code.

There are several holes. This patch reduces
the holes a bit, which reduces the size of

st/nine: Cleaning code for vs temporaries

This has been a real mess up to now: the temporaries
were allocated once, and shared after that between
the different parts of the code.

To help maintaining the code, the temporaries are now
allocated and released on need.

As surprising as it could be, this patch, which was
supposed to introduce no behaviour change, actually
solved a visual bug observed on a sample program.
This was due to ureg_normalize3 polluting a temporary
variable.

st/nine: Partial software vertex processing support

Software Vertex Processing allows:
. Less limitations for shaders (more loops, etc)
. Less limitations for ff (more enabled lights, 255
matrices for VertexBlend)

In particular shaders can get more constants.
This patch implements support for this (not using software
rendering, but hardware rendering, as llvmpipe and dx10+ hw
have the same limits...)

This is considered a second class path. Even apps asking for
"Mixed Vertex processing" (ie the ability to switch to swvp
on demand) do not use the feature much. Some just initialize
more constants than the normal limit at the start of the
application, but never use more than the normal limit.
When the apps do not need the software vertex processing
features, they do not seem to turn it on. This means it is
ok if that path is slow.
Thus no care has been made to make the path optimized.

st/nine: Initial mixed vertex processing support

In mixed vertex processing, the user can enable or disable

This feature is not a state, and thus the setting doesn't
need to be recorded by stateblocks.
