Spec tests use constants like `ref.array` and `ref.eq` to assert that exported function return references of the correct types. Support more such constants in the wast parser. Also fix a bug where the interpretation of `array.new_data` for arrays of packed fields was not properly truncating the packed data. Move the function for reading fields from memory from literal.cpp to wasm-interpreter.h, where the function for truncating packed data lives. Other bugs prevent us from enabling any more spec tests as a result of this change, but we can get farther through several of them before failing. Update the comments about the failures accordingly.
