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.

Make compiler-rt/trunk/lib/asan compileable with g++.

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!)

This patch adds two methods, __asan_allocate_island and __asan_deallocate_island
...
and switches our interceptors to using them instead of the default
vm_allocate-based approach used by mach_override_ptr.
To simplify the code, a fixed memory mapping is used for the allocation pool --
note that we can't mmap an arbitrary chunk of memory, because the shadow memory hasn't been mapped yet
(for the reasons discussed in http://code.google.com/p/address-sanitizer/issues/detail?id=24 , we cannot map the shadow earlier)
The patch drops the program startup time from several second to half a second,
which speeds up the execution of ASan tests noticeably.
Because of the virtual memory size occupied by the programs it's hard
to speed up the shutdown time, which would've also helped the tests.
