Adding an AST matcher to ignore parenthesis in *types* (rather than expressions). This is required for traversing certain types (like function pointer types).

Summary:
The switch statement could be added to the hasCondition matcher.

```
clang-query> match switchStmt(hasCondition(ignoringImpCasts(declRefExpr())))

Output:
```

The change from llvm::VariadicFunction to internal::VariadicFunction
broke the extraction of hasAnyName().
equalsNode was broken because the argument type is 'const XXXX*' and
the internal space caused a failure on the regex.

Summary: Matcher proposed in the review of checker misc-assign-operator (name pending). Its goal is to find the direct enclosing function declaration of a statement and run the inner matcher on it. Two version is attached in this patch (thus it will not compile), to be decided which approach to take. The second one always chooses one single parent while the first one does a depth-first search upwards (thus a height-first search) and returns the first positive match of the inner matcher (thus it always returns zero or one matches, not more). Further questions: is it enough to implement it in-place, or ASTMatchersInternals or maybe ASTMatchFinder should be involved?

Summary: A checker (will be uploaded after this patch) needs to check implicit casts. The checker needs matcher hasAnyArgument but it ignores implicit casts and parenthesized expressions which disables checking of implicit casts for arguments in the checker. However the documentation of the matcher contains a FIXME that this should be removed once separate matchers for ignoring implicit casts and parenthesized expressions are ready. Since these matchers were already there the fix could be executed. Only one Clang checker was affected which was also fixed (ignoreParenImpCasts added) and is separately uploaded. Third party checkers (not in the Clang repository) may be affected by this fix so the fix must be emphasized in the release notes.

Summary: A checker (will be uploaded after this patch) needs to check implicit casts. Existing generic matcher "has" ignores implicit casts and parenthesized expressions and no specific matcher for matching return value expression preexisted. The patch adds such a matcher (hasReturnValue).
