[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.

ARM: make assembly files compile Thumb2 with nop IT block.

ARM's UAL syntax allows the same assembly file to be compiled in both ARM and
Thumb mode. Conditional execution is handled by requiring the Thumb IT blocks,
but essentially ignoring them when compiling for ARM.
