Joel E. Denny a47cb644c7 [libFuzzer] Use separate test directory for each config
Previously, check-all failed many tests for me.  It was running the
X86_64DefaultLinuxConfig, X86_64LibcxxLinuxConfig, and
X86_64StaticLibcxxLinuxConfig configs out of
llvm-build/projects/compiler-rt/test/fuzzer.  Now, it runs them out of
separate subdirectories there, and most tests pass.

Petr Hosek 887f26d470 Support for multiarch runtimes layout
This change adds a support for multiarch style runtimes layout, so in
addition to the existing layout where runtimes get installed to:

lib/clang/$version/lib/$os

Clang now allows runtimes to be installed to:

lib/clang/$version/$target/lib

This also includes libc++, libc++abi and libunwind; today those are
assumed to be in Clang library directory built for host, with the
new layout it is possible to install libc++, libc++abi and libunwind
into the runtime directory built for different targets.

The use of new layout is enabled by setting the
LLVM_ENABLE_RUNTIME_TARGET_DIR CMake variable and is supported by both
projects and runtimes layouts. The runtimes CMake build has been further
modified to use the new layout when building runtimes for multiple
targets.

Kuba Mracek badaa15c88 [sanitizer] Unify and generalize Apple platforms in CMake and lit test configs
There's more platforms than just "ios" and "iossim" that we should support, and adding more lit config variables for each platform isn't great. Let's generalize and have a single value that determines what the platform under test is.

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++.

Max Moroz 1a33da2401 [libFuzzer] Fix lit files to make running tests more straightforward on Mac OS.
Summary:
Current implementation does not work if CMAKE_OSX_SYSROOT is not specified.

It silently generates invalid command with the following flags:

`-std=c++11 -lc++ -gline-tables-only -isysroot  -fsanitize=address,fuzzer`

and then fails with the following error:

```
warning: no such sysroot directory: '-fsanitize=address,fuzzer' [-Wmissing-sysroot]"
<...>/RepeatedBytesTest.cpp:5:10: fatal error: 'assert.h' file not found
#include <assert.h>
         ^~~~~~~~~~
1 error generated.
```

However, if you have Command Line Tools installed, you have '/usr/include' dir.
In that case, it is not necessary to specify isysroot path.

Also, with the patch, in case of '/usr/include' does not exist, the '-sysroot'
path would be resolved automatically in compiler-rt/cmake/base-config-ix.cmake.

For more context, see the comment at `compiler-rt/cmake/base-config-ix.cmake#L76`

Resulting library binaries will be named libclang_rt.fuzzer*, and will
be placed in Clang toolchain, allowing redistribution.
