Fix defect reported by Coverity Scan.
Macro compares unsigned to 0 (NO_EFFECT)
unsigned_compare: This greater-than-or-equal-to-zero comparison of
an unsigned value is always true. cbuf >= 0U.

When handling arrays, range is increased based on the array size minus
one. But if such is zero, it has the effect of reducing the
range. Handle that case by returning the unknown range value.

* Add missing braces.
* Return unknown range in this case, instead of keeping the initial
range.

On FMA, a carry/borrow is required for iaddc/isubb (whereas the ADD
counterparts don't support carrying/borrowing). The trick is to model
this with an extra dummy (ZERO) argument which is free to encode on FMA,
and in the scheduler, "demote" to the non-carried versions if we want to
schedule to ADD.

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).

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.
