assume that ::operator new provides no more alignment than is necessary for any primitive type, except when we're on a GNU OS, where glibc's malloc guarantees to provide 64-bit alignment on 32-bit systems and 128-bit alignment on 64-bit systems. This can be controlled by the command-line -fnew-alignment flag. llvm-svn: 282974
