New Revision: 160790

URL: http://llvm.org/viewvc/llvm-project?rev=160790&view=rev
Log:
Patch by Andrew C. Morrow:  Conditionally include cxxabi.h in new.cpp and typeinfo.cpp.  Both new.cpp and typeinfo.cpp have code that is conditionally compiled
based on the LIBCXXRT and _LIBCPPABI_VERSION defines, but those files
do not currently include <cxxabi.h> in the non __APPLE__ case. The
attached patch updates those files so that for non __APPLE__ builds
<cxxabi.h> is included if available or if LIBCXXRT is set. I'm
modeling this on the recent updates to exception.cpp.
