perf annotate: Add number of samples to the header
Staring at annotations of large functions is useless if there's only a
few samples in them. Report the number of samples in the header to make
this easier to determine.
Committer note:
The change amounts to:
- Percent | Source code & Disassembly of perf-vdso.so for cycles:u
------------------------------------------------------------------
+ Percent | Source code & Disassembly of perf-vdso.so for cycles:u (3278 samples)
+--------------------------------------------------------------------------------
