perf tools: Add ->unmap_ip operation to struct map
We need this because we get section relative addresses when reading the symtabs, but when a tool like 'perf annotate' needs to match these address to what 'objdump -dS' produces we need the address + section back again. So in annotate now we look at the 'struct hist_entry' instances (that weren't really being used) so that we iterate only over the symbols that had some hit and get the map where that particular hit happened so that we can get the right address to match with annotate. Verified that at least: perf annotate mmap_read_counter # Uses the ~/bin/perf binary perf annotate --vmlinux /home/acme/git/build/perf/vmlinux intel_pmu_enable_all on a 'perf record perf top' session seems to work.
