When we first started using genxml, we decided to represent MOCS as an
actual structure, and pack values. However, in many places, it was more
convenient to use a numeric value rather than treating it as a struct,
so we added secondary setters in a bunch of places as well.
We were not entirely consistent, either. Some places only had one.
Gen6 had both kinds of setters for STATE_BASE_ADDRESS, but newer gens
only had the struct-based setters. The names were sometimes "Constant
Buffer Object Control State" instead of "Memory", making it harder to
find. Many had prefixes like "Vertex Buffer MOCS"...in a vertex buffer
packet...which is a bit redundant.
On modern hardware, MOCS is simply an index into a table, but we were
still carrying around the structure with an "Index to MOCS Table" field,
in addition to the direct numeric setters. This is clunky - we really
just want a number on new hardware.
This patch eliminates the struct-based setters, and makes the numeric
setters be consistently called "MOCS". We leave the struct definition
around on Gen7-8 for reference purposes, but it is unused.
v2: Drop bonus "Depth Buffer MOCS" fields on Gen7.5 and Gen9

The batch decoder looks for a field with a particular name to decide
whether an MI_BB_START leads into a second batch buffer level. Because
the names are different between Gen7.5/8 and the newer generation we
fail that test and keep on reading (invalid) instructions.

MI_LOAD_REGISTER_IMM can load multiple (register, value) tuples in one
command. In our drivers we only use one tuple at a time, but the
kernel might load more than one at a time.
Instead of making all the tuple part of a group, we leave out the
first tuple (the one we use in the generated packing structures).
This is particularly useful for looking at error stats generated by
the kernel.

They serve no purpose other than to just fill empty space in the packet
so each dword has something. Just disallowing empty groups is a bit

We need to emit BLEND_STATE, which size is 1 + 2 * nr_draw_buffers
dwords (on gen8+), but the BLEND_STATE struct length is always 17. By
marking it size 1, which is actually the size of the struct minus the
BLEND_STATE_ENTRY's, we can emit a BLEND_STATE of variable number of
entries.
For gen6 and gen7 we set length to 0, since it only contains
BLEND_STATE_ENTRY's, and no other data.
With this change, we also change the code for blorp and anv to emit only
the needed BLEND_STATE_ENTRY's, instead of always emitting 16 dwords on
gen6-7 and 17 dwords on gen8+.
v2:
- Use designated initializers on blorp and remove 0 from
initialization (Jason)
- Default entries to disabled on Vulkan (Jason)
- Rebase code.
