To pick up the changes in:
2b26f0aa004995f4 ("perf: Support only inheriting events if cloned with CLONE_THREAD")
2e498d0a74e5b88a ("perf: Add support for event removal on exec")
547b60988e631f74 ("perf: aux: Add flags for the buffer format")
55bcf6ef314ae8ba ("perf: Extend PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE")
7dde51767ca5339e ("perf: aux: Add CoreSight PMU buffer formats")
97ba62b278674293 ("perf: Add support for SIGTRAP on perf events")
d0d1dd628527c77d ("perf core: Add PERF_COUNT_SW_CGROUP_SWITCHES event")
Also change the expected sizeof(struct perf_event_attr) from 120 to 128 due to
fields being added for the SIGTRAP changes.

perf record: Add dummy event during system wide synthesis2020-05-28T13:03:25ZIan Rogersirogers@google.com2020-04-22T17:36:15Zurn:sha1:0a892c1c947230f9373c9a3c94df1babe989861f
During the processing of /proc during event synthesis new processes may
start. Add a dummy event if /proc is to be processed, to capture mmaps
for starting processes. This reuses the existing logic for
initial-delay.
v3 fixes the attr test of test-record-C0
v2 fixes the dummy event configuration and a branch stack issue.
