Alexander Potapenko 49034e3c33 [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.

Kostya Serebryany f0b8f989e9 add Linux syscall wrappers and ThreadLister to sanitizer_common 
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.

Alexander Potapenko e8ba1c851a [ASan] Refactoring: nuke the redundant function declarations in asan_intercepted_functions.h 
that had been used on OS X only.
The INTERCEPTOR() macro on OS X is now responsible for declaring the wrapped function, the wrapper and the
pair of pointers to them in __DATA,__interposition section. Thus adding an interceptor requires editing a single file now.
