genxml: Fix decoding of array groups.

If you had a group as the first element of a struct, i.e.

      <field name="ReadLength" start="0" end="15" type="uint"/>
    </group>

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?".

      <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

Ben and I haven't observed these to help anything, but they enable

i965: Set the "Float Blend Optimization Enable" bit on Gen9+.

This is woefully undocumented.  It's some kind of optimization that
avoids unnecessary render target reads when blending with a floating
point render target, using independent alpha blending modes.

The internal documentation indicates that this bit exists on Cherryview
as well, but the other driver doesn't appear to set it on that platform.
There's also some confusing wording that indicates that it may exist on
Broadwell, but the documentation says it's reserved, so who knows.

I was not able to find any workload that benefited from setting this
bit, but it seems like a good idea to set it nonetheless.
