When we filter by column content we may end up with a column
that has the same value for all the lines. So remove that
column and tell its unique value on the top, as a comment.
Example:
[acme@doppio pahole]$ perf report --sort comm,dso,symbol -d ./build/libdwarves.so.1.0.0 -C pahole | head -15
# dso: ./build/libdwarves.so.1.0.0
# comm: pahole
# Samples: 58409
#
# Overhead Symbol
# ........ ......
