Alexey Samsonov ee03b5bbb9 [CMake] Unify build rules for sanitizer_common for Apple and non-Apple platforms.
Additionally, link safestack runtime on OS X with nolibc version of
sanitizer_common runtime, as we do on Linux.

Chris Bieneman d160260681 [CMake] merge add_compiler_rt_runtime and add_compiler_rt_darwin_runtime into a single function
Summary: This refactoring moves much of the Apple-specific behavior into a function in AddCompilerRT. The next cleanup patch will remove more of the if(APPLE) checks in the outlying CMakeLists.

This patch adds a bunch of new functionality to add_compiler_rt_runtime so that the target names don't need to be reconstructed outside the call. It also updates some of the call sites to exercise the new functionality, but does not update all uses fully. Subsequent patches will further update call sites and move to using the new features.

Chris Bieneman d8b76ce3bf [CMake] Backing out part of r245317. Turns out safestack and profile don't work correctly on the iOS simulator and enabling it breaks tests.

Evgeniy Stepanov 5a268b10b3 [sanitizer] Implement logging to syslog.
Previously, Android target had a logic of duplicating all sanitizer
output to logcat. This change extends it to all posix platforms via
the use of syslog, controlled by log_to_syslog flag. Enabled by
default on Android, off everywhere else.

A bit of cmake magic is required to allow Printf() to call a libc
function. I'm adding a stub implementation to support no-libc builds
like dfsan and safestack.

This is a second attempt. I believe I've fixed all the issues that
prompted the revert: Mac build, and all kinds of non-CMake builds
(there are 3 of those).

Peter Collingbourne b64d0b1e6d Protection against stack-based memory corruption errors using SafeStack: compiler-rt runtime support library
This patch adds runtime support for the Safe Stack protection to compiler-rt
(see http://reviews.llvm.org/D6094 for the detailed description of the
Safe Stack).

This patch is our implementation of the safe stack on top of compiler-rt. The
patch adds basic runtime support for the safe stack to compiler-rt that
manages unsafe stack allocation/deallocation for each thread.

Original patch by Volodymyr Kuznetsov and others at the Dependable Systems
Lab at EPFL; updates and upstreaming by myself.
