Put saved registers in *actually* the write place. I hope.

Rework the way stack frames are laid out to be simpler and, hopefully, more
...
correct. Saved registers are now placed in what may be the right place.

Actually, the locals need to go above the spills and saved regs, so fp == lb.

Lots more opcodes. Rearrange the stack layout so that fp->ab is a fixed value
...
(needed for CHAINFP and FPTOAB). Wire up lfrs to calls via a phi when
necessary, to allow call-bra-lfr chains.

Mangle label names (turns out that the ACK assembler can't really cope with
...
labels that are the same name as instructions...).

Swaps work (at least for registers). More opcodes. Rearrange the stack layout
...
so we can always trivially find fp, which lets CHAINFP work.

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!

Phi copies are now inserted as part of type inference. More opcodes.

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

Better (and more correct) floating point conversions; fif; various new opcodes.

fef4 and fef8 is now cleaner, albeit slower; add some more register alias
...
stuff.

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.

Lots more opcodes; better eviction behaviour; better register moves. Lots more
...
PowerPC stuff (some working).

Bolt mcg into the PowerPC backend. It doesn't build yet, but it is generating
...
*some* code.
