* xlat/perf_hw_id.in: Likewise.
* xlat/perf_sw_ids.in: Likewise.
* xlat/perf_type_id.in: Likewise.
* perf.c [HAVE_LINUX_PERF_EVENT_H]: Remove inclusion of

(PRINT_XLAT): New macro for simplifying printing values from
sorted xlat.
(printxlat_search): New function, wrapper for xlat_search with behaviour
similar to printval.
(print_perf_event_attr): New print_event_attr structure fetching and
printing function.
(SYS_FUNC(perf_event_open)): Use print_perf_event_attr for displaying
attr argument contents.
* tests/perf_event_open.c: Renamed to

* tests/perf_event_open.test: add -e verbose=none in order to preserve
output format being checked (in case verbose output is enabled,
contents of attr arguments are shown now); rename to
tests/perf_event_open_nonverbose.test; add -e trace=perf_event_open.
