perf tests: Do not rely on dso__data_read_offset() to open dso

2015-02-06T10:46:35Z

Do not rely on dso__data_read_offset() will always call dso__data_fd() internally. With multi-thread support, accessing a fd will be protected by a lock and it'll cause a huge contention. It can be avoided since we can skip reading from file if there's a data in the dso cache. If one needs to call the dso__data_read_offset(), [s]he also needs to call dso__data_fd() (or set dso->binary_type at least) first like the dwarf unwind code does.

perf test: Fix dso cache testcase

2015-02-06T10:46:35Z

The current dso cache permits to keep dso->data.fd is open under a half of open file limit. But test__dso_data_cache() sets dso_cnt to limit / 2 + 1 so it'll reach the limit in the loop even though the loop count is one less than the dso_cnt and it makes the final dso__data_fd() after the loop meaningless. I guess the intention was dsos[0]->data.fd is open before the last open and gets closed after it. So add an assert before the last open.
