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.

codeGenIntermediate: fold struct-array field access to single LOADX/STOREX
...
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.

...
Remove byte-offset pre-scaling from IR generation and encode
element index + explicit scale in the IR. Effective address is

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.

fix STOREZX.BYTE register type determination on m68k targets
...
STOREZX uses reg1 as the index register (not the value register),
so it should return indexRegType (WORD on 32-bit targets) regardless
of the instruction type. The code handled this for FLOAT/WORD/LONG
but missed the BYTE type case, causing register type conflicts
when indexing arrays with uword variables on m68k targets.
