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).

Support arrays of struct instances
...
- Parser: parse `StructType[N] var` via elementToArray() for
STRUCT_INSTANCE (Prog8ANTLR.g4, Antlr2KotlinVisitor)
- Desugar: struct-instance bases via addressOfStructInstance(),
whole-struct `a[i]=a[j]` -> sys.memcopy, inferred `[[...]]`
and explicit `Struct : [...]` (without ^^) for value arrays;
reject `^^Struct : [...]` in instance arrays
- 6502: computeStructArrayElementAddress() with 16-bit
index*structSize scaling (AssignmentAsmGen, AsmGen)
- IR/VM/m68k/new6502: STRUCTDEFS round-trip, loaders, gens
- AstChecker/IdentifiersChecker: reject struct fields that are
arrays of structs; fix isArray guards
- Docs: structpointers.rst/variables.rst, todo.rst, examples/test.p8
- Tests: TestArraysOfStructs (pointer vs value init, IR round-trip,
16-bit strides)
