perf annotate: Split branch stack cycles information out of 'struct annotation_line'
The cycles info is used only when branch stack is provided. Separate
them from 'struct annotation_line' into a separate struct and lazy
allocate them to save some memory.
Committer notes:
Make annotation__compute_ipc() check if the lazy allocation works,
bailing out if so, its callers already do error checking and
propagation.
