If we are out of memory, we can't try to allocate a string that could fail as well. When Error is converted to String, this would result in an endless OOM-throwing loop. Instead, pre-allocate the string on the VM, and use it to construct the Error. Note that as of this commit, the OOM string is still a DeprecatedString. This is just preporatory for Error's conversion to String.
