Function termination gets routed through an exit block; we now have prologues
...
and epilogues. mcgg now exports some useful data as headers. Start factoring
out some of the architecture-specific bits into an architecture-specific file.

Predicates can now take numeric arguments. The PowerPC predicates have been
...
turned into generic ones (as they'll be useful everywhere). Node arguments for
predicates require the '%' prefix for consistency. Hex numbers are permitted.

Instruction predicates work now.

Made sure that all files end in vim magic.

Instruction selection now happens on a shadow tree, rather than on the IR tree
...
itself. Currently it's semantically the same but the implementation is cleaner.

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.

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

Some instruction selection is now happening.

Crudely bolt on mcgg to mcg itself.
