Something wrong happened with this patch: there are tons of unrelated changes
here. Maybe you need to update your working copy?

So why do we need `isExpansionInMainFile()` here and in all other matchers?
ClangTidy has its own mechanism to filter warnings by location.

----------------
Now `processNamedCastExpr`, `processNamedCastExpr` and `processFunctionalCast`
methods are almost identical and can be replaced by a single method. And I
think this method should be `processExplicitCastExpr` that should have the same
implementation.
BTW, currently, the `processExplicitCastExpr` method can only be called if the
code encounters the only class inherited from `ExplicitCastExpr` that is not
handled explicitly: `ObjCBridgedCastExpr`.
Once again: replace `processExplicitCastExpr` implementation with this:
```
void RedundantVoidArgCheck::processExplicitCastExpr(
const MatchFinder::MatchResult &Result,
const ExplicitCastExpr *ExplicitCast) {
if (protoTypeHasNoParms(ExplicitCast->getTypeAsWritten())) {
removeVoidArgumentTokens(
Result,
ExplicitCast->getTypeInfoAsWritten()->getTypeLoc().getSourceRange(),
"cast expression");
}
}
```
... and remove the other three `process...Cast` methods and the corresponding
`if` branches.
Also, register a single `explicitCastExpr` matcher instead of separate matchers
for all kinds of casts.
