[Heap] Allow UncompiledDataWithoutPreParsedScope in LO space.

Bytecode flushing can overwrite a bytecode array with an UncompiledDataWithoutPreParsedScope.
Since the bytecode array could be in the LO space, then we also need to allow
UncompiledDataWithoutPreParsedScope in the LO space if it has overwritten a large
bytecode array.
