    llvm MIPS target: add missed source file
    
    Otherwise, linking llvm binaries with this target enabled (which is not
    the default) will fail with a number of undefined symbol errors:
    
      ld: error: undefined symbol: llvm::initializeMipsMulMulBugFixPass(llvm::PassRegistry&)
      ld: error: undefined symbol: llvm::createMipsMulMulBugPass()
    
    MFC after:      3 days
