Given a parsed instruction set definition, this script generates
instruction disassembly routines responsible for decoding instruction
words and pretty-printing. Decoding is somewhat complex as with the
previous disassembler but can be automated.
Disssembly is complicated by indirect specifications of instruction
modifiers. These specifiers are given as logic expressions in the XML,
which optimizes for straightforwaard packing but makes disassembly
awkward. Instead of attempting to invert the logic directly, we generate
lookup tables of `modifiers -> encoding` maps which we may invert
directly to produce a lookup table for the `encoding -> modifiers` map
needed for disassembly.

From the ISA definition, we can generate a function for each instruction
that looks at the bi_instruction in the intermediate representation and
emits a 20- or 23-bit word (for ADD/FMA respectively) containing that
instruction with all of its modifiers.
These will approximate the old packing routines, although the mapping of
bi_instruction to machine instructions will be hardcoded (at least for
now).

This Python script parses the ISA.xml file to produce a normalized
in-memory representation suitable for the disassembly and packing
scripts to consume. In particular, it papers over details about
duplicate encodings and default fields.

Throughout this series, this XML file will serve as architectural ground
truth. It contains every instruction in the instruction set with all
programmable modifiers, as well as logic for computing derived values
(indirectly specified modifiers) and swapping operands as needed by
numerous encodings. It also allows for multiple encodings per
instruction differentiated by exact bits (a generalization of opcodes),
with different derived fields in each encoding, and logic tests to
select between the encodings at pack time.

When minx = -32768 (ViewportBounds.Min) we'll hit the "left <= -1, ..."
assert because 'left' is computed as:
(-65535 / 2 - translate_x) / (minx - translate_x)
This commit fixes the problem by using the full max_viewport_size => [-32768, 32767]
instead of [-32767, 32767] for SI_QUANT_MODE_16_8_FIXED_POINT_1_256TH.

In !6574 I fixed the dates, but I didn't realise there was one too many
releases in the list, as `-rc3` had already been released and `-rc4` was
about to be.
`-rc4` was since released, so the next 20.2 release is now `-rc5`, and
it's slipped another week; let's update the calendar to that.

Add an allowlist to make an exception when deriving images from
interlaced buffers. Normally, the function should fail if the surface
needs to be modified to derive the image. But some applications do not
follow the fall-back method of using vaCreateImage + vaPutImage as
mentioned in the VAAPI documentation, so we have to make an exception.
