Implement counted-loop IR (IRLoopChunk)
...
Replace the early lowering of constant repeat/for loops into p8_regfile
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.

Replace arr[idx].field (arr:Struct[Sz], idx variable) from
EXT+MUL #Sz + ADDR + ADD #fieldOff + LOADI/STOREI (5 ops) to
single indexed op: LOADX/STOREX arr+fieldOff,S=Sz and
STOREZX for zero. Reuses existing ,S=N + +off encoding.

in 6502 AssignmentAsmGen.computeStructArrayElementAddress();
IR: preserve STRUCTDEFS round-trip, VM loader support;
m68k/new6502/intermediate backends; docs + todo updated.
Limitations: not as struct fields (AstChecker/
AstIdentifiersChecker error) nor as sub params.
