    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.

nir: Introduce new nir_intrinsic_load_per_vertex_input intrinsics.

Geometry and tessellation shaders process multiple vertices; their
inputs are arrays indexed by the vertex number.  While GLSL makes
this look like a normal array, it can be very different behind the
scenes.

On Intel hardware, all inputs for a particular vertex are stored
together - as if they were grouped into a single struct.  This means
that consecutive elements of these top-level arrays are not contiguous.
In fact, they may sometimes be in completely disjoint memory segments.

NIR's existing load_input intrinsics are awkward for this case, as they
distill everything down to a single offset.  We'd much rather keep the
vertex ID separate, but build up an offset as normal beyond that.

This patch introduces new nir_intrinsic_load_per_vertex_input
intrinsics to handle this case.  They work like ordinary load_input
intrinsics, but have an extra source (src[0]) which represents the
outermost array index.

By returning a nir_ssa_def *, we can pass back both an existence flag
