radeonsi: initial WIP SI code

This commit adds initial support for acceleration
on SI chips.  egltri is starting to work.

The SI/R600 llvm backend is currently included in mesa
but that may change in the future.

The plan is to write a single gallium driver and
use gallium to support X acceleration.

radeonsi: Remove unused winsys pointer

This was removed from r600g in commit:

    gallium: remove unused winsys pointers in pipe_screen and pipe_context

    A winsys is already a private object of a driver.

radeonsi: Copy color clamping CAPs from r600

Not sure if the values of these CAPS are correct for radeonsi, but the
same changed were made to r600g in commit:

    st/mesa: do vertex and fragment color clamping in shaders

    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.

radeonsi: Remove PIPE_CAP_OUTPUT_READ

This CAP was dropped in commit:

commit 04e324008759282728a95a1394bac2c4c2a1a3f9
Author: Marek Olšák <[email protected]>
Date:   Thu Feb 23 23:44:36 2012 +0100

    gallium: remove PIPE_SHADER_CAP_OUTPUT_READ

    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.

radeonsi: Add missing parameters to rws->buffer_get_tiling() call

This was changed in commit:

commit c0c979eebc076b95cc8d18a013ce2968fe6311ad
Author: Jerome Glisse <[email protected]>
Date:   Mon Jan 30 17:22:13 2012 -0500

    r600g: add support for common surface allocator for tiling v13

    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

    Revert "gallium: add flag PIPE_TRANSFER_MAP_PERMANENTLY"

    This reverts commit 0950086376b1c8b7fb89eda81ed7f2f06dee58bc.

    to address the performance issues.
