* `--mca ompi_display_comm VALUE` where `VALUE` is one or more of:
- `mpi_init` : Display during `MPI_Init`
- `mpi_finalize` : Display during `MPI_Finalize`
* hook/comm_method: Use enum flags to select protocols

Remove some left-over infrastructure for handling callbacks into the
MPI C++ bindings (which were removed long ago -- this code is now
stale).

The test now has the ability to add a shift to all or to any of the
input and output buffers to assess the impact of unaligned operations.

1. Allow fallback to a lesser AVX support during make
Due to the fact that some distro restrict the compiule architecture
during make (while not setting any restrictions during configure) we
need to detect the target architecture also during make in order to
restrict the code we generate.
2. Add comments and better protect the arch specific code.
Identify all the vectorial functions used and clasify them according to
the neccesary hardware capabilities.
Use these requirements to protect the code for load and stores (the rest
of the code being automatically generated it is more difficult to
protect).
3. Correctly check for AVX* support.

1. Consistent march flag order between configure and make.
2. op/avx: give the option to skip some tests
it is possible to skip some intrinsic tests by setting some environment variables to "no" before invoking configure:
- ompi_cv_op_avx_check_avx512
- ompi_cv_op_avx_check_avx2
- ompi_cv_op_avx_check_avx
- ompi_cv_op_avx_check_sse41
- ompi_cv_op_avx_check_sse3
3. op/avx: update AVX512 flags
try
-mavx512f -mavx512bw -mavx512vl -mavx512dq
instead of
-march=skylake-avx512
since the former is less likely to conflict with user provided CFLAGS
(e.g. -march=...)
Thanks Bart Oldeman for pointing this.
4. op/avx: have the op/avx library depend on libmpi.so

* PGI was throwing the following error.
```
NVC++-S-0103-Illegal operand types for comparison operator (osc_rdma_frag.h: 75)
NVC++/power Linux 20.11-0: compilation completed with severe errors
```
* It must not have liked the inline declaration of the NULL pointer.
- So replace with a variable, as we do in other places in the code base.

Currently, mca_btl_ofi_put (get, aop, afop, acswp) will allocate
a mca_btl_ofi_rdma_completion_t object and use it as the context
for fi_write/fi_read/fi_atomic/fi_fetch_atomic/fi_compare_atomic.
In normal code path, this completion object when processing completion
entry. However, when error happened when calling
fi_write/fi_read/fi_atomic/fi_fetch_atomic/fi_compare_atomic,
there will be no completion entry from libfabric, in this case the
completion object's memory is leaked.
This patch address the issue by calling opal_free_list_return() in
the error handling code path.
