Remove -Mipa=fast as a default flag and add it as an option instead.
-Mipa=fast is a flag that speeds up runtime but at the cost of significant
compile time increase and therefore, shouldn't be a default flag.
In addition, -Mipa isn't supported on PGI OpenPOWER or x86/llvm compilers.
Since commit v3.9.0-rc1~17^2~4 (Compilers: Port to use default
cmake_record_lang_compile_features macros, 2017-05-10) we run full
per-language-standard feature detection for MSVC. This is not necessary
because the base mode for MSVC has all features we define except for the
meta-features for C++14 and above. Override the default C++ feature
detection macro for MSVC to run detection only once as before.
Fixes: #17274
flang is a Fortran compiler built on top of clang [1]. Because flang
shares a lot of commonalities with clang, the flang module piggybacks
off the clang module and overrides certain options.
Add flang to Fortran compiler auto find list.
Update flang preprocessor macros to differentiate from PGI.
Add Flang-FindBinUtils.

The Ninja generator preprocesses and compiles separately for Fortran.
When compiling, tell gfortran that the source is already preprocessed so
that it will honor the `# <line>` directives when producing diagnostics
messages.

Debian renames all LLVM/Clang binaries with a version suffix to allow
multiple versions to be installed at the same time. While there is a
version-agnostic package that adds a symlink to provide the standard
binary names, if only the versioned packages are installed, binaries
must be found as `binary-x.y`. In any case, using the same version of
the `binutils` as the compiler seems better.
Set the variable added by commit a2112257 (Add infrastructure to use
language extensions without any standard, 2017-06-29) for IAR. This was
accidentally left out of commit d8e6cd9e (IAR: Improve support for IAR
ARM Compiler, 2017-06-15).
Visual Studio 2015 Update 3 introduced the notion of language standard
levels to MSVC. The language standard level is defined in `_MSVC_LANG`
instead of `__cplusplus`. It also added support for the `-std:c++14`
and `-std:c++latest` flags, although the compiler defaults to its C++14
mode anyway. Visual Studio 2017 Update 3 will introduce support for the
`-std:c++17` flag.

Make the implementation for this compiler more complete.
IAR has multiple C++ modes, historically they were reduced c++ versions
for embedded that gradually improved to the full standard (which can be
reduced again by e.g. disabling rtti and exceptions). The new
implementation picks the best available, but the c++ mode can also be
overridden by defining `CMAKE_IAR_CXX_FLAG`.
Add C/C++ standard flags so that all modes up to and including the last
supported standard are defined.
Fixes: #16826
We only define `INTERPROCEDURAL_OPTIMIZATION` behavior for C, CXX, and
Fortran languages. Do not try to enable support for other languages.
Furthermore, each language builds with a different compiler, so check
for support by CMake and the compiler for each language independently.
Fixes: #16944
There are no specific options for MSVC to set language standards, but
set them as empty strings anyways so the feature test infrastructure
can at least check to see if they are defined.
Add default implementations for the cmake_record_lang_compile_features
macros. All implementations of this are the same so it can be safely
factored out to a common implementation.

In the bootstrap script, we want to be able to extract language standard
flags using sed. Make sure the content of the flag varianbles can be
passed unmodified to the compiler.
PGI demands -Bdynamic (/MD equivalent) for linking together dynamic
libraries, so we should make it our default mirroring the settings of
e.g. Visual C++ and Intel C++.
By using only -F, SunPro does not process files that don't have a .F or
.F90 extension. This means that the preprocess rules don't quite work as
expected, for instance breaking the Ninja generator's behavior during
cmake_ninja_depends.
