Michal Gorny ef4b600301 [test] Add missing cmake include for building libFuzzer alone
Include CompilerRTCompile in fuzzer tests explicitly.  Otherwise, when
building only libFuzzer, CMake fails due to:

CMake Error at cmake/Modules/AddCompilerRT.cmake:395 (sanitizer_test_compile):
  Unknown CMake command "sanitizer_test_compile".
Call Stack (most recent call first):
  lib/fuzzer/tests/CMakeLists.txt:53 (generate_compiler_rt_tests)

Petr Hosek 466f0f028a [compiler-rt][Fuzzer] Fix the fuzzer test build
This fixes the issue introduced in r345765 which changed the way in
which the embedded libc++ is being built but omitted tests.

Matt Morehouse 7e042bb1d1 [libFuzzer] Port to Windows
Summary:
Port libFuzzer to windows-msvc.
This patch allows libFuzzer targets to be built and run on Windows, using -fsanitize=fuzzer and/or fsanitize=fuzzer-no-link. It allows these forms of coverage instrumentation to work on Windows as well.
It does not fix all issues, such as those with -fsanitize-coverage=stack-depth, which is not usable on Windows as of this patch.
It also does not fix any libFuzzer integration tests. Nearly all of them fail to compile, fixing them will come in a later patch, so libFuzzer tests are disabled on Windows until them.

Matt Morehouse 0948bc2086 [libFuzzer] Do not turn unittest warnings into errors.
Some warnings originating from googletest were causing bots to fail
while bulding unit tests.  The sanitizers address this issue by not
using -Werror.  We adopt this approach for libFuzzer.

Petr Hosek 2d19f9036e [Fuzzer] Avoid the unnecessary rebuild of the custom libc++
This changes the add_custom_libcxx macro to resemble the
llvm_ExternalProject_Add. The primary motivation is to avoid
unnecessary libFuzzer rebuilds that are being done on every
Ninja/Make invocation. The libc++ should be only rebuilt whenever
the libc++ source itself changes.

Petr Hosek 066e4bf888 Reland "[Fuzzer] Parametrize add_custom_libcxx"
add_custom_libcxx uses the just built compiler and installs the
built libc++, e.g. for testing, neither of which is desirable in
case of Fuzzer where the libc++ should be built using the host
compiler and it's only linked into the libFuzzer and should never
be installed. This change introduces additional arguments to
add_custom_libcxx to allow parametrizing its behavior.

Petr Hosek eac2b47b9f Reland "[libFuzzer] Support using libc++"
This is needed in case the users of libFuzzer use libc++ in their
code, which the fuzz target (libFuzzer) will be linked against.
When libc++ source is available, we build a private version of it
and link it against libFuzzer which allows using the same static
library against codebases which use both libc++ and libstdc++.
