Fix QML compiler crashes on big endian systems
Commit be491913c036b148 changed QV4::CompiledData::Unit to use LEUInt32
structures internally, rather than native uints, however the generators
were not updated at that time and still wrote native uints.
Also initialize constants field of CompilationUnit to prevent crashes
in unlink() where operator delete[] is called.
