[CMake] Add experimental support for building compiler-rt for iOS
Summary:
This is a reunification of three separate reviews D11073, D11082, D11083.
Having them separate was not constructive even though the patches were smaller because it led to fragmented conversations, and this is really all about one change.
This patch incorporates feedback from samsonov, and refactors the hacky darwin code out of the root CMakeLists.txt and int config-ix.cmake.

[CMake] Disable building all Darwin libraries (except builtins) for macOS i386 when the SDK is >= 10.15.
Summary:
In the macOS 10.15 SDK the ability to link i386 binaries was removed and
in the corresponding OS it is not possible to run macOS i386 binaries.
The consequence of these changes meant that targets like `check-asan`
would fail because:
* Unit tests could not be linked for i386
* Lit tests for i386 would fail due to not being able to execute
compiled binaries.
The simplest fix to this is to simply disable building for i386 for
macOS when using the 10.15 SDK (or newer). This disables building the
i386 slice for most compiler-rt libraries and consequently disables the
unit and lit tests for macOS i386.
Note that because the `DARWIN_osx_ARCHS` CMake variable is a cache
variable this patch will have no affect on existing builds unless
the existing cache variable is deleted. The simplest way to deal with
this is delete existing builds and just do a fresh configure.
Note this should not affect the builtins which are managed with
the `DARWIN_osx_BUILTIN_ARCHS` CMake cache variable.
For those who wish to force using a particular set of architectures when
using newer SDKs passing `-DDARWIN_osx_ARCHS=i386;x86_64;x86_64h` to
CMake should provide a usable (but completely unsupported) workaround.

the existing cache variable is deleted. The simplest way to deal with
this is delete existing builds and just do a fresh configure.
Note this should not affect the builtins which are managed with
the `DARWIN_osx_BUILTIN_ARCHS` CMake cache variable.
For those who wish to force using a particular set of architectures when
using newer SDKs passing `-DDARWIN_osx_ARCHS=i386;x86_64;x86_64h` to
CMake should provide a usable (but completely unsupported) workaround.

[CMake] Add experimental support for building compiler-rt for iOS
Summary:
This is a reunification of three separate reviews D11073, D11082, D11083.
Having them separate was not constructive even though the patches were smaller because it led to fragmented conversations, and this is really all about one change.
This patch incorporates feedback from samsonov, and refactors the hacky darwin code out of the root CMakeLists.txt and int config-ix.cmake.

[compiler-rt] respect CMAKE_EXE_LINKER_FLAGS in compiler and library tests
Summary: check_cxx_compiler_flag and check_library_exists could fail because they ignored CMAKE_EXE_LINKER_FLAGS and therefore would always fail to produce executables. Cmake policy CMP0056 fixes this, but was explicitly set to OLD in our CMakeLists because it caused problems with test_target_arch. This change sets the policy to NEW to fix the problem with the compiler and library tests, and temporarily clears CMAKE_EXE_LINKER_FLAGS inside test_target_arch to emulate the old behavior there. This allows, for example, LTO builds that require lld to succeed.

Specify log level for CMake messages (less stderr)
Summary:
Specify message levels in CMake. Prefer STATUS (stdout).
As the default message mode (i.e. level) is NOTICE in CMake, more then necessary messages get printed to stderr. Some tools, noticably ccmake treat this as an error and require additional confirmation and re-running CMake's configuration step.
This commit specifies a mode (either STATUS or WARNING or FATAL_ERROR) instead of the default.
* I used `csearch -f 'llvm-project/.+(CMakeLists\.txt|cmake)' -l 'message\("'` to find all locations.
* Reviewers were chosen by the most common authors of specific files. If there are more suitable reviewers for these CMake changes, please let me know.
