Fixed ArrayLiteralExp::toConstElem for dynamic arrays, tango-user library should now be possible to build. It seems to be related to DMD bug 2356, which must have been introduced recently, as we already handled this fine for ArrayInitializers, just not ArrayLiterals... Kinda annoying to have to do this work due to DMD bugs ...
