The loop cloner assumes all computations it introduces are compatible with TYP_INT, so don't allow cloning when the initial or final value are variables with incompatible types. Fixes #57535.

Customer Impact
Already reported by one customer (in 6p7). Caused crossgen2 to fail.
Testing
Verified it fixes the customer issue, plus new tests added. No diffs in existing tests (per SPMI).
Risk
Low, this is a change to disable an optimization in an uncommon situation.
