Subject: [PATCH 34/53] perf report: Move symbol annotation to the resort phase

From: Jiri Olsa <jolsa@...nel.org>

Currently we make the annotation for the IPC column during the entry
display, already outside of the progress bar scope, so it appears like
'perf report' is stuck.

Move the annotation retrieval to the resort phase, so that all the data
are ready for display.
