Android uses libgcc name even for shared library unlike other platforms
which use libgcc_s. Furthemore, Android libstdc++ has a dependency on
libdl. These need to be handled while performing CMake checks.

Currently there's a large amount of CMake logic duplication for
compiling sanitizer tests.
If we add more sanitizers, the duplication will get even worse.
This change factors out common compilation commands into a macro
available to all sanitizers.

This change adds support for compiler-rt builtins as an alternative
compiler runtime to libgcc.

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 improves find_darwin_sdk_dir to cache the results of executing xcodebuild to find the SDK. Should significantly reduce the CMake re-configure time.

Adds a CMake option DARWIN_PREFER_PUBLIC_SDK, off by default. When on, this prefers to use the public SDK, even when an internal one is present. With this, it's easy to emulate a build that the public buildbots are doing.

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. These test suites are not added into "check-all" or into "check-asan", they have to be run manually.

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:
Adds a new cmake flag 'COMPILER_RT_ENABLE_LSAN_OSX', which enables lsan
compilation and is turned off by default. Patches to fix build errors
when this flag is enabled will be uploaded soon.
This is part of an effort to port LSan to OS X, but LSan on OS X does not
currently work or pass tests currently.
