Peter Collingbourne 3498a1ac52 Use _CPPUNWIND instead of _HAS_EXCEPTIONS with MSVC. 
_HAS_EXCEPTIONS is specific to the MSVC STL and defining it to 0 causes
problems with libc++, so libc++ users may leave it undefined. This can
cause GTEST_HAS_EXCEPTIONS to be defined incorrectly if the user has
disabled exceptions via the compiler, which can lead to build errors.

_CPPUNWIND is a builtin macro provided by the compiler so it should
work with both STLs.

Peter Collingbourne ba99a04be2 Check whether _MSC_VER is defined when detecting presence of cxxabi.h under libc++. 
If _MSC_VER is defined, it means that we are using the Microsoft
ABI, so cxxabi.h (which is associated with the Itanium ABI) will not
be available.
