Perform SSA conversion of locals. Much, *much* better code now, at least
...
inasmuch as it looks better before register allocation. Basic blocks now know
their own successors and predecessors (after a certain point in the IR
processing).

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).

We're going to need some type inference after all, I think. Let's do a little
...
for now and see how it goes.

You know what, the type inference stuff is a complete red herring. What this
...
actually needs is a more intelligent register allocator. So, remove the type
inference.

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

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.

Some instruction selection is now happening.

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.
