use arm shift at runtime
...
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

putstring unfolds length
...
which means sys call doesn’t need to
and also interpreter sometimes gets a symbol length

fix the putstring sys call indexing
...
index 0 is the marker word , so like in some, all indexes 1 based
works :-)

by having a dummy 0 index in salaam. when assembled

fix arm indexes
...
needs rethought
fixed for static use, but what about dynamic

implement arm branches
...
which backfired into interpreter as
plus actually means 0 or plus in arm
may still change back but for now

update arm and implement most operators
...
multiplication wasn’t implemented
and division isn’t part if arm
neither is rotate by register

add set_internal
...
and the set_slot with register
very much like the get_slot for get_internal

use translator and remove passes
...
the only passes that were left were reg -> arm
those are almost completely one to one, so the idea of passes didn’t fit
