- Remove a duplicate "Configure host" output line
- No longer show the OPAL version. Since OPAL has never separated
into its own project, its version is always the same as Open MPI.

Looks like this script was left over from quite a long time ago, and
was expecting CLI params from the "old"-style Automake test engine.
Update it to look for `--test-name` to get the test name, and update a
few other minor style things.

Even if the compiler supports an "alternate" short float type (e.g.,
_Float16), check to make sure that the compiler will correctly link
applications that perform mathematical operations on that type.
Carefully choose the mathematical test in the configure check to
ensure the mathematical operation is not removed by compiler
optimization (when setting CFLAGS=-O1 or higher).
Out of the box, clang 6.0.x and 7.0.x will fail to link applications
that try to perform addition (and other mathematical operations) on
_Float16 variables (an additional CLI flag is required to enable
software emulation of _Float16). If we detect a situation where the
type is supported by a sample program fails to link and the basename
of $CC is "clang", emit a warning and point the user to a relevant
README.

Keep all comments in the user-facing mpi.h.in as "old style" C
comments: /* */. This gives us maximum portability, just on the off
chance that a user's C compiler does not support //-style comments.

1. __STDC_VERSION__ isn't necessarily defined (e.g., by C++
compilers). So check to make sure it is defined before we actually
check the value.
2. If we're in C++11 (or later), use static_assert().
3. Split the static assert macro in two macros:
* THIS_SYMBOL_WAS_REMOVED_IN_MPI30(...): Insert a valid expression
(i.e., 0, because it's only used with MPI_Datatype values, and
since MPI_Datatype is a pointer, 0 is a valid RHS expression)
before invoking the static assert so that we don't get a syntax
error instead of the actual static assert error.
* THIS_FUNCTION_WAS_REMOVED_IN_MPI30(...): No need for the valid
expression; just invoke the assert functionality.
Also remove an errant "\".
Thanks to Constantine Khrulev and Martin Audet for identifying the
issue and suggesting to use C11's static_assert().

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
