Mechanical change to sink a #ifdef guard for a platform below the
...
include of int_lib.h.
The purpose of this change is to make the C code conform to the pedantic
rules of C99 -- an empty translation unit is not valid. It should have
absolutely no functional impact, and changes nothing about the built
libraries.

Actually intercept free() to ensure that the deallocations caused by other functions directly calling it are routed to our allocator.
...
For the allocations that do not belong to any malloc zone check whether they're padded with a pointer to ASan's CFAllocator. If so, free the original (unpadded) pointer.
This should fix AddressSanitizerMac.NSURLDeallocation and issue 70.

Resuming work on the compiler-rt CMake build at long long last. In order
...
to get it working again, two changes were needed:
- I had to give up on glob-based file expansion. This just isn't well
supported by CMake, and until we convince upstream there of its value,
it's not worth dealing with the pain.
- Add the common library as otherwise even ASan won't build.
This now builds again, although the "correctness" of it is a touch
debatable. ;] Specifically, there is no merging of the common runtime
library with the asan runtime library into a single archive file. I'm
not really sure what the best technique is for that, and it may be
influenced by the ongoing discussion about how best to link runtime
libraries.
Note of course that this is still very much WIP. It doesn't entirely
work yet, and remains disabled by the LLVM projects/CMakeLists.txt until
it is in a working state.
