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.

Limitations: not as struct fields (AstChecker/
AstIdentifiersChecker error) nor as sub params.
