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
When this property is set, the test is skipped and its status is
automatically set to 'Not Run'. A disabled test will not be counted in
the total number of tests and its completion status will be 'Disabled'.
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.
Fixes: #16745
The VS generators use the C (or CXX) preprocessor definitions for
the Windows Resource Compiler tool. This causes definitions parsed
out of `CMAKE_RC_FLAGS[_<CONFIG>]` variables to be dropped. Fix
the implementation to preserve both.
Issue: #16745
The `TargetExt` for `.vfproj` object libraries should be `.lib`
to match the `OutputFile` value. Otherwise Visual Fortran raises
warnings:
TargetPath(...) does not match the Library's OutputFile
property value (...)
