Simpleperf: adjust sort strategy in RecordCache.
In order to report correctly, We should keep the order of self created
records when reading perf.data. So adjust sort strategy in RecordCache
to avoid reordering it.

Simpleperf: do stack unwinding while recording.
Dumping user's stack consumes lots of disk space, which makes long period recording
impossible. This patch does stack unwinding before writing to perf.data, so it doesn't
need to save user's stack. Previous behavior is still supported with --post-unwind option.
A record cache is used for online record processing.
