This fixes the existing workaround in {BytecodeGraphBuilder} where the
number of elements in an array literal is unknown just from the bytecode
alone and needs to be deduced from the constant elements.
Note that this is just a quick fix to prevent calling the fast-clone
stub for boilerplates that are too big to fit on a regular page. In the
long run we need something more solid here.
