Disable wrapping memcpy() on Mac OS Lion, where it
...
actually falls back to memmove.
In this case we still need to initialize real_memcpy, so we set it to
real_memmove
We check for MACOS_VERSION_SNOW_LEOPARD, because currently only Snow
Leopard and Lion are supported.

Make compiler-rt/trunk/lib/asan compileable with Visual Studio 2008 on Windows.
...
Patch by Timur Iskhodzhanov (timurrrr@google.com )
To test:
$ cl /c *.c*
in the asan directory.
The code fails to link if you omit the "/c" part but that's one of the
next steps,
as well as a few TODO's I've put into the Windows-specific code.

Patch by Timur Iskhodzhanov (timurrrr@google.com )
The double-extern thing is
http://llvm.org/bugs/show_bug.cgi?id=11869
And the #include <string[s].h> are only needed on Mac (see comments in
the original code)
and also including them might make strchr/index conflict with the g++
system headers (which don't follow the man pages, ouch!)

Add a test for CFStringCreateCopy.

Normally this function should not create copies of constant strings, but it does when the default CFAllocator
is replaced (e.g. under AddressSanitizer)
