Introduce a new CMake option `COMPILER_RT_SANITIZERS_TO_BUILD` which takes
either a special token `all` (default) which will preserve the current behaviour
or a CMake list of sanitizers to build. It will still perform the normal checks
if the sanitizer is requested. It only permits a further means to exclude a
particular sanitizer. This gives finer grained control than
`COMPILER_RT_BUILD_SANITIZERS` which only gives an all or nothing control.

This fixes a long-standing TODO by implementing a compiler check for supporting the _Atomic keyword. If the _Atomic keyword is supported by the compiler we should include it in the builtin library sources.

differ from the way Clang/LLVM are grouping targets.

This macro is called from the base config, so it can't live in config-ix, it needs to be in the utils. I suspect the only reason this hasn't caused problems is that nobody is building the Android builtins from the builtins subdirectory.
llvm-svn: 271693
Summary:
When using a multi-configuration build (i.e. MSVC) the output path where
libraries are dropped is incorrect.
Example:
```
C:\src\llvm\examples>d:\src\llvm\build\Release\bin\clang-cl.exe -fsanitize=address test.cc
LINK : fatal error LNK1181: cannot open input file 'd:\src\llvm\build\Release\bin\..\lib\clang\3.9.0\lib\windows\clang_rt.asan-i386.lib'
```
The dropped executable path contains the configuration 'Release':
```
'd:\src\llvm\build\Release\bin\..\lib\clang\3.9.0\lib\windows\Release\clang_rt.asan-i386.lib'
```
The variable 'RUNTIME_OUTPUT_DIRECTORY' is used to specify the output directory.
But CMAKE is appending the current configuration (i.e. Debug, Release).
see: https://cmake.org/cmake/help/v3.0/prop_tgt/RUNTIME_OUTPUT_DIRECTORY.html
```
"Multi-configuration generators (VS, Xcode) append a per-configuration subdirectory to the specified directory."
```
To avoid this problem, the configuration specific variable must be set:
'RUNTIME_OUTPUT_DIRECTORY_DEBUG', 'RUNTIME_OUTPUT_DIRECTORY_RELEASE', and so on.

Summary:
One of the big limitations we have in the compiler-rt build system today is that we cannot bootstrap building the builtins because you need a fully functional toolchain to pass CMake's tests.

It is NFC because nothing is using the compile-only tests yet.

This commit changes the strategy for building shared ASan runtime
and the way we test it:
- COMPILER_RT_BUILD_SHARED_ASAN CMake option is removed. We now
always build shared ASan runtime (it is the default on Android,
Windows and Mac, and not the default on Linux and FreeBSD).
- Platforms, which use static runtime by default now have
"check-asan-dynamic" testsuite. This testsuite contains instrumented
unit tests, and ASan lit tests, and runs them with shared ASan
runtime. This testsuite is *not* a part of "check-asan" and
*not* a part of "check-all", as adding 1000 more test cases, which
duplicate existing ones is costly. However, you're welcome to
add this command to your buildbot.

When CMake builds a dynamic library on Windows, the .dll file's location is

for sanitizers to pass the C++ compilation and exe linking flags through

This change lets MSan rely on libcxx's own build system instead of manually

Patch by Brad King.
Our add_sanitizer_rt_symbols macro reads the LOCATION property of a
library to compute the location of the "lib<name>.a.syms" file to
generate next to the corresponding "lib<name>.a" library file. CMake
3.0 introduces policy CMP0026 to disallow reading of the LOCATION target
property from non-imported targets in favor of the more powerful
$<TARGET_FILE> generator expression.
Teach add_sanitizer_rt_symbols to use the $<TARGET_FILE> generator
expression to compute the location of the symbols file to generate
with a custom command. CMake 3.0 also adds support for generator
expressions to install(FILES) so use it when available to simplify
installation of the symbols file of the proper configuration.
llvm-svn: 202797
Patch by Brad King.
When using a multi-config generator with CMake, such as for VS or Xcode,
the LOCATION target property value contains a placeholder such as
"$(Configuration)" that is meant for substitution by the native build
tool. The install(FILES) command does not understand this name and will
not install the symbols file correctly when using these generators.
Teach add_sanitizer_rt_symbols to read the more-specific target property
LOCATION_<CONFIG> that has a per-configuration value and no placeholder.
On single-configuration generators (Makefile, Ninja), CMAKE_BUILD_TYPE
contains the name of the one configuration to be built. On multi-config
generators (VS, Xcode), CMAKE_CONFIGURATION_TYPES contains the list of
possible configurations. In the latter case, loop over the configs and
add a configuration-specific install(FILES) rule for each one.
Place the code block inside an if(TRUE) block so it can be made
conditional in a following change without updating indentation.
