From: Alexei Starovoitov <ast@fb.com>
[ Upstream commit 569cc39d39385a74b23145496bca2df5ac8b2fb8 ]
llvm cannot always recognize memset as builtin function and optimize
it away, so just delete it. It was a leftover from testing
of bpf_perf_event_output() with large data structures.
Fixes: 39111695b1b8 ("samples: bpf: add bpf_perf_event_output example")
