gallium: add PIPE_RESOURCE_FLAG_TEXTURING_MORE_LIKELY

For performance tuning in drivers. It filters out window system
framebuffers and OpenGL renderbuffers.

radeonsi will use this to guess whether a depth buffer will be read
by a shader. There is no guarantee about what will actually happen.

This is a departure from PIPE_BIND flags which are defined to be strict
but they are useless in practice.

On Intel Pineview M hardware, the i915 gallium driver doesn't output

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

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: Use NineDevice9_CreateDepthStencilSurface in swapchain9

Replace custom code with NineDevice9_CreateDepthStencilSurface.
All functionality is given now.

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.
