[sanitizer] Android build cleanup.
...
* Detect Android toolchain target arch and set correct runtime library name.
* Merged a lot of Android and non-Android code paths.
* Android is only supported in standalone build of compiler-rt now.
* Linking lsan-common in ASan-Android (makes lsan annotations work).
* Relying on -fsanitize=address linker flag when building tests (again,
unification with non-Android path).
* Runtime library moved from lib/asan to lib/linux.

[ASan] Add CMake configs for libclang_rt.asan_iossim_dynamic.dylib
...
CMake changes to build the ASan runtime for the iOS simulator. This is a universal library targeting the same architectures as the OSX ASan runtime does, thus the iossim version can't live in the same universal libclang_rt.asan_osx_dynamic.dylib
The difference between the OSX and iossim builds is in the -mios-simulator-version-min and -ios_simulator_version_min flags that tell Clang to compile and link iossim code.
The iossim runtime can only be built on a machine with both Xcode and the iOS Simulator SDK installed. If xcodebuild -version -sdk iphonesimulator Path returns a nonempty path, it is used when compiling and linking the iossim runtime.

ThreadLister is a Linux-specific class for obtaining the thread IDs of a process from procfs (/proc/<pid>/task/). It will be used by leak checking code.
Also add several syscall wrappers which will be required by the same code that uses ThreadLister, but are not used in ThreadLister itself.
