The variables recently added by commit b9d36826 (Add 'CMAKE_GCC_AR' and
'CMAKE_GCC_RANLIB' variables, 2017-03-08) are more appropriately managed
with language-specific names rather than toolchain-specific names.
The `ld` tool in Xcode 8.3 now has a `-lto_library <path>` flag. Ignore
the flag instead of accidentally parsing it as `-l` with `to_library`.

Intel 17.0.2 on UNIX introduced a regression from 17.0.1 in its
definition of `__cpp_constexpr` in `-std=c++14` mode. It incorrectly
defines it as `200704` instead of the expected `201304`. Fix our
feature detection table to account for this.
The change in commit v3.8.0-rc2~7^2 (ExternalProject: Run `git
checkout` with `--` to clarify arguments, 2017-02-24) broke the case of
`GIT_TAG some-remote-branch` because an explicit `--` means that the
preceding argument is a tree-ish instead of a branch. Revert the change
and leave a comment.

During compiler identification, extract the Xcode `CURRENT_ARCH` value
and save it for later use by the Xcode generator in an internal compiler
information variable. This will be useful to know the locations of
object files when only one architecture is built.

Previously the `INTERPROCEDURAL_OPTIMIZATION` target property was
honored only for the Intel compiler on Linux and otherwise ignored. In
order to add support for more compilers incrementally without changing
behavior in the future, add a new policy whose NEW behavior enforces the
`INTERPROCEDURAL_OPTIMIZATION` property. Add flags for supported
compilers and otherwise produce an error.

CMakeDetermineSystem.cmake uses "uname -r" to get
CMAKE_HOST_SYSTEM_VERSION on AIX. AIX uses "uname -v" for the
major version and "uname -r" for the minor version.
Thanks to Chris Taylor for the suggested patch.
Closes#10749
The sdcc compiler no longer defines the `SDCC` preprocessor macro.
Instead `__SDCC_VERSION_MAJOR` and similar component-wise macros are
defined. Use them instead if defined.
Issue: #16746
In commit v3.8.0-rc1~304^2 (MSVC: Do not define _DEBUG explicitly when
using /MDd, 2016-11-15) we removed the `_DEBUG` preprocessor definition
from MSVC C and C++ flags because the `cl` compiler automatically
defines it in Debug builds anyway. However, the VS generators propagate
C preprocessor definitions to the RC (Windows Resource Compiler) tool.
This means that we used to explicitly define `_DEBUG` for RC debug
builds. Therefore existing project code may expect the definition to be
there even though the `rc` compiler itself does not implicitly define
`_DEBUG` in debug builds.
Add the `_DEBUG` flag to the default `CMAKE_RC_FLAGS_DEBUG` instead
to restore this definition for RC debug builds. This also makes it
available consistently in VS, Ninja, and Makefile generators.

VS 2017 (VS 15) places its redist DLLs in `Microsoft.VC150.*`
directories but still uses version number `140` in the DLL names. The
redist directories now have version numbers in their name, and the MSVC
and MFC runtime DLLs may be in directories with different versions.
Fill out our logic to handle this.
For now assume we are given the `MSVC_REDIST_DIR` value as a cache
entry. Unfortunately we cannot yet find the VS 2017 MSVC redist
directory automatically since there is no registry entry for the VS
installation. Later we will have to use `cmVSSetupHelper` for this.
