Now Open MPI requires a C99 compiler. Checking availability of
the following types is no more needed.
- `long long` (`signed` and `unsigned`)
- `long double`
- `float _Complex`
- `double _Complex`
- `long double _Complex`

the following types is no more needed.
- `long long` (`signed` and `unsigned`)
- `long double`
- `float _Complex`
- `double _Complex`
- `long double _Complex`
Furthermore, the `#if HAVE_[TYPE]` style checking is not correct.
Availability of C types is checked by `AC_CHECK_TYPES` in `configure.ac`.
`AC_CHECK_TYPES` defines macro `HAVE_[TYPE]` as `1` in `opal_config.h`
if the `[TYPE]` is available. But it does not define `HAVE_[TYPE]`
(instead of defining as `0`) if it is not available. So even if we
need `HAVE_[TYPE]` checking, it should be `#if defined(HAVE_[TYPE])`.
I didn't remove `AC_CHECK_TYPES` for these types in `configure.ac`
since someone may use `HAVE_[TYPE]` macros somewhere.

This commit fixes an compilation error when configured
with `--enable-timing`.
Procedures in the function `orte_ess_base_app_setup`
in `orte/mca/ess/base/ess_base_std_app.c` are moved
to `orte/mca/ess/pmi/ess_pmi_module.c`
and `orte/mca/ess/singleton/ess_singleton_module.c`
in the recent commit 57f6b94fa5.
In `ess_pmi_module.c`, the first argument of the
`OPAL_TIMING_ENV_NEXT` macro should have been adapted
to the destination function but was not.
In `ess_singleton_module.c`, `OPAL_TIMING_ENV_INIT`
was not used in the destination function originally.
So `OPAL_TIMING_ENV_NEXT` cannot be used in the function.

Update the show_help message for when there are not enough slots to
run an application.
Also, remove a bunch of copies of this message in various show_help
text files that aren't used/referred to anywhere in the code.

Per feedback from https://github.com/open-mpi/ompi/pull/6028, remove
"+ob1" from the sentence to emphasize that it's only IB usage through
openib that is deprecated/superceded (i.e., ob1 is definitely not
deprecated).

It seems in some cases (gcc older than v6.0.0) the __atomic_thread_fence is a
no-op with __ATOMIC_ACQUIRE. This appears to be the case with X86_64 so go
ahead and use __ATOMIC_SEQ_CST for the x86_64 read memory barrier. This should
not cause any performance issues as it is equivalent to the memory barrier
in the hand-written atomics.
