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.

ir: add scaled indexing (S=) to LOADX/STOREX/STOREZX
...
Remove byte-offset pre-scaling from IR generation and encode
element index + explicit scale in the IR. Effective address is
base + index*scale + disp (disp = symbolOffset).

Add arrays of struct instances (StructType[N] vars)
...
Parser: accept `Type[N] name` between type and identifier
(Prog8ANTLR.g4, Antlr2KotlinVisitor) via elementToArray()
for STRUCT_INSTANCE; CodeDesugarer: handle struct-instance
bases, addressOfStructInstance(), whole-struct memcopy
(points[a]=points[b]), and fix variable-index 16-bit scaling
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.
