[MS ABI] Update EH emission for MSVC 2015 compatibility MSVC 2015 renamed the symbol found by name lookup for 'std::terminate' so we cannot rely on using '?terminate@@YAXXZ'. Furthermore, it seems that 2015 will be the first release of MSVC which permits inlining a function which is noexcept into a function which isn't. This is implemented by creating a cleanup for the invoker which jumps to __std_terminate. Clang's implementation of this aspect of the MSVC scheme is slightly less efficient in this respect because we use a catch handler configured as a catch-all handler instead. llvm-svn: 236961
