perf record: Synthesize non-exec MMAP records when --data used
When perf_event_attr.mmap_data is set the kernel will generate
PERF_RECORD_MMAP events when non-exec (data, SysV mem) mmaps are
created, so we need to synthesize from /proc/pid/maps for existing
threads, as we do for exec mmaps.
Right now just 'perf record' does it, but any other tool that uses
perf_event__synthesize_thread(s|map) can request it.
