The PAPI support in the RTS allows users to collect a group of preset PAPI
events (e.g. {{{PAP_TOT_CYC}}}). However, PAPI can also collect data for
native events exposed by the hardware beyond the PAPI present events. The
native events supported on your hardware can found by using the
{{{papi_native_avail}}} tool. It would be great if the RTS allows users to
collect native events along with the preset events.

Changes (by dmp):
* status: new = patch
Comment:
Attaching a patch that extends PAPI support to allow users to specify
native events.
The changes included are:
1) New option (#) for the RTS PAPI flag for native events. For example,
to
collect the native event 0x4000, use {{{./a.out +RTS
-a#0x4000 -sstderr}}}
2) Update the PAPI_FLAGS struct to store whether the user specified
event is a
papi preset or a native event
3) Update init_countable_events function to add the native events after
parsing
the event code and decoding the name using PAPI_event_code_to_name
The patch validates against HEAD. The validation script does not by
default enable PAPI support so the changes do not really get tested by a
validate. It also validates after enabling PAPI support, but that requires
another (unrelated) patch to get validate to work with PAPI enabled (see
#4151).
