More rigorous dealing of IR groups; no need for is_generated and is_root any
...
more (but now passes are required to set IR roots properly when changing
instructions).

Predicates work; we now have prefers and requires clauses. Predicates must be
...
functions. Not convinced that semantic types are actually working --- there are
still problems with earlier statements leaving things in the wrong registers.

Much better handling of fragments (no run-time code needed to distinguish them
...
from registers) and better handling of individual hops within a paragraph ---
no more ghastly hacks to try and distinguish the input from the output.

Actually, I don't need vregs: hops work just as well. Particularly if I
...
restructure things so that I don't need to walk the blasted ir / burg tree
every time I look at an instruction.

Fleshed out hops and vregs. The result is almost looking like code now ---
...
uncanny.

Revamp the array module not to use nasty macros any more. Slightly more verbose
...
to use, but definitely cleaner.

Start factoring out the hardware op code.

Sort of keep track of registers and register classes. Start walking the
...
generated instruction tree --- holy cow, they look like instructions!

Collapse several rule arrays into one; actually generate the array properly.

We now record the code fragments to be emitted by each rule.

Instruction selection is so important the file needs a longer name.
