This CL fixes an issue where V8 does not satisfy the WebAssembly spec of
the anyref proposal.
The table.fill instruction has 3 parameters, {start_index}, {length},
and {value}. V8 trapped with table-out-of-bounds when
{start_index >= table_size}. However, the spec requires that
{start_index == table_size} is valid when {length == 0}.
