Procedure compilation now happens after the entire EM file has been read in (so
...
that we can look inside data blocks which might be defined in the future...
sigh, csa and csb). csa and csb no longer generate invalid IR.

Replaced the block splicer with a trivial block eliminator (which rewrites
...
jumps to blocks which contain only a jump). Don't bother storing the bb graph
in the ir nodes; we can find it on demand by walking the tree instead ---
slower, but much easier to understand and more robust. Added a terrible map
library.

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.

Create hacky fake basic blocks for data fragments, used to track which

Massive ackbuilder refactor --- cleaner and more expressive. Lists

Fix a whole pile of issues related to the failed attempt to increase

the number of types of relocation possible in the object file. (Now,

Also change the object serialiser/deserialiser to never try to read or
