Fix poke->assignment optimizer dropping AddressOf index
...
StatementOptimizer rewrote pokel(&arena[1], x) to arena = x, ignoring
AddressOf.arrayIndex (and dereference), which miscompiled implicit
indexed-base struct field writes such as arena[1].s = X. All four
poke/pokew/pokel/pokef rewrites now require a plain variable address.

Implement counted-loop IR (IRLoopChunk)

counter sequences with a first-class IRLoopChunk that carries the trip
count and body. This removes the fragile REGFILE-DEPENDENT m68k dbra
peephole and gives each backend explicit control.
