Cloned `CallNode` gets a fresh `CallGenerator` which has to be put on `_print_inlining_list` when -XX:+PrintInlining is used.

Otherwise, if the  `CallGenerator` ends up on `_late_inlines` list (which is processed by `Compile::process_late_inline_calls_no_inline()`, `Compile::print_inlining_move_to()` can't locate it in `_print_inlining_list` and triggers the crash. 

The fix is to put cloned `CallGenerator` next to original one in `_print_inlining_list`.
