[1/5] perf annotate: Split struct cycles_info
Commit Message
The cycles info is used only when branch stack is provided. Split them
into a separate struct and lazy allocate them to save some memory.

Shouldn't we stop here and tell the user that his system is really tight
on memory instead of just ignoring it?
if (al->cycles == NULL) {
ui__error("Not enough memory for allocating branch stack cycles info!\n");
return ... its a void function :-\
}
Since its a void function, can't we detect that we need al->cycles
allocated at the tool start and allocate it there, then propagate back
the error?
Its per line, so doing it lazily is indeed easier, so make that function
return an error and bail out when not being able to calculate the ipc
for the remaining lines?

I.e. with this folded into this patch, all but one of the callers of
symbol__annotate2() already call a ui error messagem for instance:
err = symbol__annotate2(ms, evsel, opts, &browser.arch);
if (err) {
char msg[BUFSIZ];
dso->annotate_warned = true;
symbol__strerror_disassemble(ms, err, msg, sizeof(msg));
ui__error("Couldn't annotate %s:\n%s", sym->name, msg);
