commit f4d91a5df8b749c6cdfec25e38a44c02c90ad4be

Bug #358213 helgrind/drd pthread_barrier tests vs new glibc implementation
glibc 2.23 will have a new pthread_barrier implementation.
This implementation reacts differently on bad usage of barriers.
Because of this the bar_bad testcase will hang indefinitely.
In particular pthread_barrier_destroy will hang when there are
still other threads waiting on a barrier. To solve this we add
extra threads to will "unblock" the hanging destroy by sleeping
for a while and then also waiting on the barrier, which will unblock
the destroy operation. Or if this is the last test, just exit
the whole program since we are done anyway. Also newer glibc is
more picky about destroying uninitialized barriers, we would crash
when zero filling, so we now one fill. Which doesn't crash, but
depending on glibc version might return an error or hang. Since
depending on version we now get slightly different error reports
there are now alternative exp files.
Tested against glibc 2.17, glibc 2.22 and glibc 2.23-prerelease.
