mcgg now checks that registers have at most one type attribute set.

Remove the bytes1, bytes2, bytes4, bytes8 attributes; remove the concept of a
...
register 'type'; now use int/float/long/double throughout to identify
registers. Lots of register allocator tweaks and table bugfixes --- we now get
through the dreading Mathlib.mod!

Re-re-add the type inference layer, now I know more about how things work.
...
Remove that terrible float promotion code.

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.

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.
