Namhyung Kim 4ef032d899 perf annotate: Split branch stack cycles info from 'struct annotation' ...

[ Upstream commit b7f87e3259 ]

The cycles info is only meaningful when sample has branch stacks.  To
save the memory for normal cases, move those fields to a new 'struct
annotated_branch' and dynamically allocate it when needed.  Also move
cycles_hist from annotated_source as it's related here.
