Like in 'perf report' and 'perf top', Add this option to limit the
number of functions it displays based on the overhead value in percent.

This affects only stdio and stdio2 output modes.  Without this, it
shows very long disassembly lines for every function in the data
file.  If users don't want this behavior, they can set a value in
percent to suppress that.
