These targets strip during installation, and are required to support
install-distribution-stripped in LLVM (to support a stripped
distribution). LLVM has an add_llvm_install_targets function for this
purpose, but we can't rely on LLVM being present.

This renames ASM_TSAN_SYMBOL and ASM_TSAN_SYMBOL_INTERCEPTOR to just ASM_SYMBOL and ASM_SYMBOL_INTERCEPTOR, because they can be useful in more places than just TSan. Also introduce a CMake function to add ASM sources to a target.

Summary:
Some architecture-specific function overrides (for example, i386/ashrdi3.S)
duplicate generic functions (in that case, ashrdi3.c). Prevent duplicate definitions

Summary:
Recent changes canonicalized clang_rt library names to refer to
"i386" on all x86 targets. Android historically uses i686.
This change adds a special case to keep i686 in all clang_rt
libraries when targeting Android.

Remove the explicit i686 target that is completely duplicate to
the i386 target, with the latter being used more commonly.
1. The runtime built for i686 will be identical to the one built for
i386.
2. Supporting both -i386 and -i686 suffixes causes unnecessary confusion
on the clang end which has to expect either of them.
3. The checks are based on wrong assumption that __i686__ is defined for
all newer x86 CPUs. In fact, it is only declared when -march=i686 is
explicitly used. It is not available when a more specific (or newer)
-march is used.
Curious enough, if CFLAGS contain -march=i686, the runtime will be built
both for i386 and i686. For any other value, only i386 variant will be
built.

The problem is that CMake is mostly imperative and the result of
processing "if (TARGET blah)" checks depends on the order of import of
CMake files.
In this case, "projects" folder is registered before "tools",
and calling "CheckClangHeaders" [renamed to have a better name]
errors out without even giving Clang a chance to be built.
This, in turn, leads to libFuzzer bot failures in some circumstances on
some machines (depends on whether LIT or UNIT tests are scheduled
first).

CMake's add_custom_target is considered to be *always* out of date.
This patch changes it to a combination of add_custom_target and
add_custom_command which actually tracks dependencies' timestamps.
On my machine this reliably saves 6-7 seconds on each test group.
This can be a large difference when debugging small tests.

into a function.
Most CMake configuration under compiler-rt/lib/*/tests have
almost-the-same-but-not-quite functions of the form add_X_[unit]tests
for compiling and running the tests.
Much of the logic is duplicated with minor variations across different
sub-folders.
This can harm productivity for multiple reasons:
For newcomers, resulting CMake files are very large, hard to understand,
and hide the intention of the code.
Changes for enabling certain architectures end up being unnecessarily
large, as they get duplicated across multiple folders.
Adding new sub-projects requires more effort than it should, as a
developer has to again copy-n-paste the configuration, and it's not even
clear from which sub-project it should be copy-n-pasted.
With this change the logic of compile-and-generate-a-set-of-tests is
extracted into a function, which hopefully makes writing and reading
CMake much easier.

This patch addresses two issues:
Most of the time, hacks with `if/else` in order to get support for
multi-configuration builds are superfluous.
The variable `CMAKE_CFG_INTDIR` was created precisely for this purpose: it
expands to `.` on all single-configuration builds, and to a configuration
name otherwise.
The `if/else` hacks for the library name generation should also not be
done, as CMake has `TARGET_FILE` generator expression precisely for this
purpose, as it expands to the exact filename of the resulting target.

This patch adds a basic support for running the ASan lit test suite against an iOS Simulator. This is done by generating more lit.site.cfg configurations into subdirectories such as IOSSimI386Config and IOSSimX86_64Config.

Summary: Currently, we build the compiler-rt runtimes with link-time optimization if LTO is configured for the LLVM project. This will break external programs that don't invoke the linker in such a way that it supports LLVM's LTO. To avoid this, this change causes the compiler-rt runtimes to be compiled with -fno-lto. This also makes the check-profile tests work on systems when doing a lld LTO build on a system where the system linker does not support LLVM LTO.

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.

Summary:
Hi Michal,
Would you be able to review this simple fix, please?
Since r291504 compiler-rt uses `llvm-config --cmakedir` to get the path to the LLVM CMake modules.
On Windows this option returns Windows style path with backslashes. CMake treats backslashes as beginning of an escaped character and thus fails to append the path to `CMAKE_MODULE_PATH`.
