// contains a message type with one of the following names:
// MockCodeGenerator_Error: Causes Generate() to return false and set the

// MockCodeGenerator_Exit." to stderr and then calls exit(123).
// MockCodeGenerator_Abort: Generate() prints "Saw message type
// MockCodeGenerator_Abort." to stderr and then calls abort().
// MockCodeGenerator_HasSourceCodeInfo: Causes Generate() to abort after
// printing "Saw message type MockCodeGenerator_HasSourceCodeInfo: FOO." to
// stderr, where FOO is "1" if the supplied FileDescriptorProto has source
// code info, and "0" otherwise.
