When testing removing perf_env with asan I noticed a number of test
failures either because of asan issues or because of building with
NO_LIBELF=1 and NO_LIBBPF=1 to avoid false memory leaks. Address these
issues so that real test failures stand out.

Ian Rogers (6):
  perf symbol: Fix use-after-free in filename__read_build_id
  perf test demangle-java: Don't segv if demangling fails
  perf symbol: Move demangling code out of symbol-elf.c
  perf intel-tpebs: Avoid race when evlist is being deleted
  perf test intel-pt: Skip jitdump test if no libelf
  perf test trace_summary: Skip --bpf-summary tests if no libbpf
