Register spilling to the stack frame works, more or less.

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.

Allow asm names for registers which are different from the friendly names shown
...
in the tracing (because PowerPC register names are just numbers).

Keep track of register types as well as attributes --- the type being how we
...
find new registers when evicting values. Input constraints work (they were
being ignored before). Various bug fixing so they actually work.

Calculate phi congruency groups; use them to solve the
...
importing-hreg-from-the-future problem (probably poorly).

Basic register allocation works!

Overhaul of everything phi related; critical edge splitting now happens before
...
anything SSA happens; liveness calculations now look like they might be
working.

Better management of register data. Add struct hreg.
