odls/alps: minor config cleanup
Add missing header to tarball. Remove stale opal_unignore
Allow the use of the optimized used timers
Cleanup the AMD64 timer function.
Minor cleanups.
Allow for native timer (cycle level) integration
for MPI_Wtime and MPI_Wtick.
Reenable the integration of OPAL level timers with
MPI_Wtime and MPI_Wtick.
Merge branch 'topic/accurate_timers'
Remove useless header.
Fix few typos.
Add tests for vector type.
Per Dave suggestion add a serializing instruction bundled
together with RDTSC. It is still not perfect, but hopefully
much better than before.
On Darwin make sure the field we expect to be 0 is indeed 0.
Cleanup the clobber list.
