[compiler-rt] Extend Mac OS versions to Yosemite

[kubamracek]

Summary

This also fixes the test/asan/TestCases/Darwin/malloc_zone-protected.cc test failure on OS X 10.10.

[kubamracek]

Also, for the sake of not breaking the ">=" version checks with every OS X release, I think we should have something like:

enum MacosVersion {
  MACOS_VERSION_UNINITIALIZED = 0,
  MACOS_VERSION_UNKNOWN,
  MACOS_VERSION_LEOPARD,
  MACOS_VERSION_SNOW_LEOPARD,
  MACOS_VERSION_LION,
  MACOS_VERSION_MOUNTAIN_LION,
  MACOS_VERSION_MAVERICKS,
  MACOS_VERSION_YOSEMITE,
  MACOS_VERSION_UNKNOWN_NEWER,
};

...
switch (version[0]) {
  case '9': return MACOS_VERSION_LEOPARD;
  case '1': {
    switch (version[1]) {
      case '0': return MACOS_VERSION_SNOW_LEOPARD;
      case '1': return MACOS_VERSION_LION;
      case '2': return MACOS_VERSION_MOUNTAIN_LION;
      case '3': return MACOS_VERSION_MAVERICKS;
      case '4': return MACOS_VERSION_YOSEMITE;
      case '5'...'9': return MACOS_VERSION_UNKNOWN_NEWER;
      default: return MACOS_VERSION_UNKNOWN;
    }
  }
  default: return MACOS_VERSION_UNKNOWN;
}
