• platform/DeprecatedString.cpp: compile-time assert to make sure sizeof(DeprecatedChar) == 2
• platform/DeprecatedString.h: pack DeprecatedChar struct to ensure that sizeof(DeprecatedChar) == 2. Move _internalBuffer in DeprecatedStringData to the end, to avoid crashes on ARM due to different struct packing.
