Add logic to handle different architectural capabilities
Detect the compiler flags necessary to build specialized
versions of the MPI_OP. Once the different flavors (AVX512,
AVX2, AVX) are built, detect at runtime which is the best
match with the current processor capabilities.
Add validation checks for loadu 256 and 512 bits.
Add validation tests for MPI_Op.

This commit updates the btl interface to change the parameters
passed to receive callbacks. The interface used to pass the tag,
a btl base descriptor, and the callback context. Most of the
values in the btl base descriptor were unused and only helped
simplify the callbacks from the self btl. All of the arguments
have now been replaced with a single receive callback descriptor.
This descriptor contains the incoming endpoint, data segment(s),
tag, and callback context. All btls have been updated to use
the new callback and the btl interface version has been bumped
to v3.2.0.
As part of this change the descriptor argument (and the segments
contained within it) have been marked as const. The were treated
as const before but this change could allow the compiler to make
better optimization decisions and will enforce that the callback
does not attempt to change the data in the descriptor.

ompi_mtl_portals4_get_endpoint() was incorrectly making a direct
call to ompi_mtl_portals4_add_procs(). Instead use the actve PML
to call add_procs(). If add_procs() fails, call ompi_rte_abort()
to terminate the job.

This is a fix based on a bugreport on github/mailing list from CGNS.
The core of the problem was that different processes entered different branches of
our aggregator selection logic, due to the fact that in some cases processes had
a matching file_view size and contiguous chunk size (thus assuming 1-D distribution),
and some processes did not (thus assuming 2-D distribution). The fix is to calculate
the avg. file view size across all processes and use this value, thus ensuring that
all processes enter the same branch.
Fixes issue #7809

Once any number of events are read, return immediately, rather than
waiting for fi_cq_read() to return FI_EAGAIN or an error. This can
improve observed latency if the user application is in a blocking call
waiting for us to return. Deleting the while loop here also means
ofi_progress_event_count serves as an upper bound for the total number
of events read in a single call (with the while loop we might read far
more, as long as new events continue to arrive).
