The folded callchain mode prints all chains in a single line.
Currently perf report --tui doesn't support folded callchains. Like
flat callchains, only leaf nodes are added to the final rbtree so it
should show entries in parent nodes. To do that, add flat_val list to
struct callchain_node and show them along with the (normal) val list.
For example, folded callchain looks like below:
$ perf report -g folded --tui
