fa86fc564aea4e40c89f6fc889e6a5bf817634b3 is the first bad commit
commit fa86fc564aea4e40c89f6fc889e6a5bf817634b3

    r600g: build fetch shader from vertex elements

    Vertex elements change are less frequent than draw call, those to
    avoid rebuilding fetch shader to often build the fetch shader along
    vertex elements. This also allow to move vertex buffer setup out
    of draw path and make update to it less frequent.

    Shader update can still be improved to only update SPI regs (based
    on some rasterizer state like flat shading or point sprite ...).
