suggest that add lambda function
```
auto reportWarningUnsupportType = [&](bool ShouldEmitWarning, char * Msgsg) {
if (ShouldEmitWarning)
M.getDiags().Report(D->getLocation(), diag::warn_toc_unsupported_type)
<< GVId << Msg;
}
```
and all the following report warnning can write as something like
`reportWarningUnsupportType ( EmitDiagnostic, "of incomplete type");`
