Precisely one stack hreg gets allocated for each vreg/congruence group for
...
eviction; this prevents us from having to worry about moving values from stack
slot to stack slot, which is hard.

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!

Add (pretty crummy) support for register aliases and static pairs of registers.
...
We should have enough functionality now for rather buggy 8-bit ints and
doubles. Rework the table and the platform.c to match.

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.
