Chandler Carruth b156b56a28 Revert r163411 based on review discussion. 
In code review, it looked like these warnings do not actually fire with
modern Clang or GCC. However, the pragma is flat out rejected by GCC in
many configurations (-Werror) so it ended up causing more problems than
it fixed.

Daniel agreed with reverting this, but I think didn't have time to get
to it.

Chandler Carruth 1aa4fef601 Relocate the external headers provided by ASan and the common sanitizer 
library.

These headers are intended to be available to user code when built with
AddressSanitizer (or one of the other sanitizer's in the future) to
interface with the runtime library. As such, they form stable external
C interfaces, and the headers shouldn't be located within the
implementation.

I've pulled them out into what seem like fairly obvious locations and
names, but I'm wide open to further bikeshedding of these names and
locations.

I've updated the code and the build system to cope with the new
locations, both CMake and Makefile. Please let me know if this breaks
anyone's build.

The eventual goal is to install these headers along side the Clang
builtin headers when we build the ASan runtime and install it. My
current thinking is to locate them at:

  <prefix>/lib/clang/X.Y/include/sanitizer/common_interface_defs.h
  <prefix>/lib/clang/X.Y/include/sanitizer/asan_interface.h
  <prefix>/lib/clang/X.Y/include/sanitizer/...

But maybe others have different suggestions?

Fixing the style of the #include between these headers at least unblocks
experimentation with installing them as they now should work when
installed in these locations.

Chandler Carruth c1c9d5818f Some flag cleanup for the sanitizer runtimes. 
This hoists most of the CFLAGS into a common variable. It also adds
detection for -Wno-c99-extensions and uses it to silence a pile of
warnings.

Finally, it switches to the proper flag -rdynamic.

With this, the cmake build is warning free on my bootstrap Linux build.
