Set current_function_has_unbounded_dynamic_stack_size to 1 when pushing a
variable-sized argument onto the stack.
if (current_function_has_unbounded_dynamic_stack_size)
stack_usage_kind = DYNAMIC;
else
stack_usage_kind = DYNAMIC_BOUNDED;

You can compile eg. zstd project with "CC="gcc -fstack-usage" make -j6 -B" and
then grep "bounded" . -R and you will find some examples of dynamic,bounded.
