Rework all the ackbuilder scripts not to use wildcards, because we can't expand
...
them without luaposix, which isn't available (easily) on OSX or Windows.

Hacky workaround the way the Modula-2 compiler generates non-standard sized
...
loads and saves. More opcodes; simplified table using macros.

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.

Keep more data around about ir instructions. Implement a half-baked type
...
inference routine to propagate information about floats up the tree, so we know
whether to put floats into special registers as early as possible.

Stupid stringlist is stupid. Use a proper data structure, properly abstracted
...
out (so other things can use it).

Rethink the way patterns are mapped to rules; generate emitters (probably
...
badly).

Some instruction selection is now happening.

IR codes are now owned by mcgg; ir terminals are inserted into the table during
...
compilation (so you can refer to them).

Crudely bolt on mcgg to mcg itself.

Massive grammar overhaul and refactor. Hacked in support for predicates, where
...
instructions can be turned on and off based on their parameters. New lexer
using a lexer. Now quite a lot of the way towards being a real instruction
selector.
