In make_image_for_buffer(), use VK_IMAGE_USAGE_SAMPLED_BIT when
transferring from the buffer and use VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT
when transferring to the buffer.
Similar to 9ffc1049ca (freedreno/ir3: use nir two-sided-color lowering).
No piglit regression.

Bring the following commit over to i915:

i965: Drop broken front_buffer_reading/drawing optimization.
Not sure if it might fix anything, but since the i965 and i915 used to
share a bunch of that code, it would seem reasonable the same problems
could be present in the i915 code still, and the i965 approach is well
tested by now so bringing it over seems fairly safe.
No piglit regressions on 855.

The hardware can draw lines 0.5 to 7.5 pixels wide. Adjust the limits
to 1.0-7.0. The old limits seems to be from the era when i915 and i965
were sharing this code.
Not really sure if 1.0-7.0 is correct. Maybe it could be 0.5.7.5 as
those are the hw limits, or maybe some combination of the two?

so if we don't need it in intel_tris.c we don't need it in
intel_render.c either, which means we can allow intel_render.c to render
points.

intelFastRenderClippedPoly() renders the polygon using triangles. For
polygons the provoking vertex is always the first one, and currently
this function assumes that the provoking vertex for triangles is the
last one. In case the user changed the provoking vertex convention,
the hardware may be configured to treat the first vertex of triangles
as the provoking vertex. So check the convention and emit the triangles
in the appropriate order to avoid having to change the hardware
provoking vertex convention for rendering polygons.

From http://lists.freedesktop.org/archives/mesa-dev/2015-May/084883.html:
"There are no real error cases here, just dead code.
validate_render() is supposed to make sure we never call these
functions if the code can't actually render the primitives. The
fprintf()+return branches should really just contain assert(0) or
equivalent."
I also rearranged the if-else-block in render_quad_strip_verts to look
more like the other functions. A future patch is going to change a
bunch of that code anyway.
