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

# Types:
#
# I, F, L, D: int, float, long, double
# i, F: int, float; promoted to long, double based on size
# .: ignore this parameter
# ?: pull/push types from other ? parameters
IR codes are now owned by mcgg; ir terminals are inserted into the table during compilation (so you can refer to them).

Massive change to how IR types are handled; we use the type code for matching rather than the size. Much cleaner and simpler.

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.
