Fix range-based 'for' loop with 'continue' in range bounds

1. Search for increment function in range element type, not in inferred
induction variable type
(which can be inappropriate, e.g., 'Nothing' in case of 'continue').

2. Handle nested loops with shared exit labels
(generated by JVM_IR for KT-37370 case).
