use MPI_MIN instead of MPI_MAX when appropriate, otherwise
a currently used CID can be reused, and bad things will likely happen.

This commit improves and corrects error handling. In
cases where existing objects are altered after a call
to ompi_java_exceptionCheck, the results of the exception
check method are checked. In the case of an exception,
memory is cleaned up and the code returns to Java without
altering existing objects.

This commit updates the intercomm allgather to do a local comm bcast
as the final step. This should resolve a hang seen in intercomm
tests.

there is no reason to invoke WAIT_SYNC_SIGNALED(sync) before

this commit initializes sync->signaled to true unless the count is zero.
Thanks George for the review and guidance.
We commonly see messages on the users list where a peer has hung up
because it has crashed. Instead of having just a BTL_ERROR message,
make this a real opal_show_help() message that tells the user that the
peer unexpectedly hung up, and they should look into *why* that peer
hung up.

This commit adds selective use of a compiler-specific pragma to
silence the numerous warnings the Sun/Oracle/Studio compilers emit for
the GNU-style inline asm used in atomic.h.
Thanks Paul Hargrove for the initial patch and the guidance.
This commit contains the following changes:
- There is a bug in the PGI 16.x betas for ppc64 that causes them to
emit the incorrect instruction for loading 64-bit operands. If not
cast to void * the operands are loaded with lwz (load word and
zero) instead of ld. This does not affect optimized mode. The work
around is to cast to void * and was implemented similar to a
work-around for a xlc bug.
- Actually implement 64-bit add/sub. These functions were missing and
fell back to the less efficient compare-and-swap implementations.
Thanks to @PHHargrove for helping to track this down. With this update
the GCC inline assembly works as expected with pgi and ppc64.

It looks like one help message was accidentally pasted in the middle
of another. Disentangle the two messages from each other, and
slightly tweak the one message to say that the job may also crash (in
addition to hanging).

We disabled this support a long time ago. Probably safe to assume
whatever bug we were working around no longer exists.
