[mips] Make TTypeEncoding indirect to allow .eh_frame to be read-only.
Summary: Following on from r209907 which made personality encodings indirect, do the same for TType encodings. This fixes the case where a try/catch block needs to generate references to, for example, std::exception in the .gcc_except_table.
