feels like wip, but passes (all but one)

Fix word offset
...
which had weirdly been 1 off
(not weird that it was off, index bugs are common, but weird that the tests passed anyway)

hacking method not found
...
was using exit, since raise is not implemented. This was ambiguous as all programs exit.
Using :died as special kernel code and bending it, and reporting it in interpreter.

fix dynamic call
...
which had the method in the regsiter, not the binary.
Single SlotToReg added (and some tests)
Which amazingly fixed all broken binary tests

fix the exit sequence
...
was returning wrong register (1, not 0)
also saving the message for test, which changes order as the return value destroys the message

write adjusted address

1k hurray

Torsten Ruger

give labels an integer that will end up being the position at runtime
...
Since integers are first class objects, we need to use an integer object
as the return address. The actual address can not be stored in an
instance variable since it is not an object.
The address is unique to the label and never changes after positioning
(using the int is next up)

rename set_slot

set_slot was clear about the target, but not the source.
Better with reg_to_slot (and soon it’s inverse slot_to_reg)

arm indexes are in bytes (x4) at compile time
but at runtime we only have the array indexes, iw word indexes
arm has the nice barrel shifter to save us an extra instruction
