ir: store FileInfo string in escaped format (#1690)
This should speed up the common case as the compiler never operates on the unescaped string. The new escape function also fixes a bug where ']' was not escaped even though it is the delimiting character for FileInfo. In order to maintain backwards compatibility for the ProtoBuf format, this patch adds escape/unescape calls when going from/to protobuf format. For better performance we should consider changing the protobuf format.
