perf record: Store data mmaps for dwarf unwind
Currently we don't synthesize data mmap by default. It depends on -d option, that enables data address sampling. But we've seen cases (softice) where DWARF unwinder went through non executable mmaps, which we need to lookup in MAP__VARIABLE tree. Making data mmaps to be synthesized for dwarf unwind as well.
