We were only using it for validating that we don't use Ys/Yf on gen8 and
earlier. Removing it from isl_tiling_get_info lets us remove it from a
bunch of other things that had no business needing a hardware
generation.

If you had a group as the first element of a struct, i.e.
<struct name="3DSTATE_CONSTANT_BODY" length="10">
<group count="4" start="0" size="16">
<field name="ReadLength" start="0" end="15" type="uint"/>
</group>
...
</struct>
we would get a group_offset of 0, causing create_field() to think the
field wasn't in a group, and fail to offset forward for successive array
elements. So we'd mark all the array elements as offset 0.
Using ctx->group->elem_size is a better check for "are we in a group?".

If you have something like:
<group count="0" start="96" size="32">
<field name="Entry_0" start="0" end="15" type="GATHER_CONSTANT_ENTRY"/>
<field name="Entry_1" start="16" end="31" type="GATHER_CONSTANT_ENTRY"/>
</group>
We would reset ctx->group_count to 0 after processing the first field,
so the second would not have a group count.
This is largely untested, as the only groups with multiple fields are
packets we don't emit in Mesa. Found by inspection.

We can just update the gl_transform_feedback_info fields at link time
to make the VUE header fields have the right location and component.
Then we don't need to handle them specially at draw time, which is
expensive.

Ben and I haven't observed these to help anything, but they enable
hardware optimizations for particular cases. It's probably best to
enable them ahead of time, before we run into such a case.

Gen6+ support multiple scissor rectangles, and define a SCISSOR_RECT
structure containing their dimensions. On Gen4-5, those same fields
exist in SF_VIEWPORT.
This patch extracts the SF_VIEWPORT fields into a SCISSOR_RECT
structure. Although not a named concept on Gen4-5, it works just
as well, and gives us a consistent SCISSOR_RECT structure across
all generations, making it easier to reuse code.

Scalar mode has been default since Broadwell, and vector mode is getting
increasingly unmaintained. There are a few things that don't even fully
work in vector mode on Skylake, but we've never cared because nobody
uses it. There's no point in porting it forward to new platforms.
So, just ignore the debug options to force it on.

Due to complications with things such as URB setup on gen4-5, it's
easier to keep gen4 support in blorp completely internal to i965. This
makes things a bit awkward because that means there's a file in i965
that includes blorp_priv.h but it's either that or have a file in blorp
that includes brw_context.h.
