Features recorded by commit v3.6.0-rc1~120^2~5 (Features: Record
standards and features for Intel C++ on UNIX, 2016-04-28) for the Intel
compiler left out initializer list support because our test case in
`Tests/CompileFeatures/cxx_generalized_initializers.cpp` caused an
internal compiler error. It turns out this is because the Intel
compiler asserts the `initializer_list` constructor signatures to verify
that they match its own `<initializer_list>` header. It was our dummy
implementation used to test the language feature without any headers
that caused the ICE. Revise it to use a constructor signature accepted
by the Intel compiler.
Fixes: #17829
IBM XL C/C++ for Linux versions 13.1.6 and above no longer define
`__IBMC__` or `__IBMCPP__` by default (see `-qxlcompatmacros`).
Instead `__ibmxl__` now identifies the compiler along with some
related new version macros.
Fixes: #17784
In commit v3.11.0-rc1~466^2 (Compiler/TI: Add support for depfile
generation for Ninja, 2017-10-16) the flag for C++ was added in a
variable with a typo in its name. Fix the spelling.

The `CMakeASMInformation` module warns when no compiler-specific module
is found for the `ASM` language. Add a minimal `Compiler/MSVC-ASM`
module to avoid the warning for MSVC.

The IAR compiler test works when a project specifies LANGUAGES C CXX
but fails if CXX comes before C. This change makes it work regardless
of the order.

This was done for C++ by commit v3.5.0-rc1~69^2 (Record compile features
for MinGW Clang on Windows, 2016-01-11). Make the same change for C.
The `UNIX` condition on Clang C compiler features was already dropped by
refactoring in commit v3.9.0-rc1~17^2~4 (Compilers: Port to use default
cmake_record_lang_compile_features macros, 2017-05-10).
Our documentation already claims support for this combination. This
was simply an oversight when support was added for MinGW Clang C++.

In `CMakeFortranCompilerId.F.in`, take the `_MSC_VER` out of the
Intel-specific block so it will trigger for other compilers like Flang.
In `Compiler/Clang.cmake`, switch off Fortran too.
In the normal archiving rules the ``<CMAKE_AR>`` placeholder is replaced
by the generators with a properly-quoted path to the tool. In the IPO
rules we specify the tools directly, so we need to quote them.
Fixes: #17326
`__IAR_SYSTEMS_ICC__` provides additional version information that
we need to determine correct usage of the compiler. Extract and
store it as `CMAKE_<LANG>_COMPILER_VERSION_INTERNAL`.
Issue: #17264
Starting in CUDA 9 the default compilation mode is C++14, and you need
to explicitly enable C++98/03 mode.
While at it, document `14` among the values for `CUDA_STANDARD`. This
was accidentally left out of commit v3.9.0-rc1~118^2 (CUDA: Add support
for the C++14 standard flag, 2017-05-11).
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.
Fixes: #17160
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
