[PATCH] D21241: Add an ASTMatcher for ignoring ExprWithCleanups.

I was wondering why we didn't created that Matcher: IgnoreImplicit

I believe it's more commonly used than 'ignoringExprWithCleanups'.

It can be implemented by calling 'Stmt.IgnoreImplicit'.

  /// Skip past any implicit AST nodes which might surround this
  /// statement, such as ExprWithCleanups or ImplicitCastExpr nodes.
  Stmt *IgnoreImplicit();

nit: you can lift that expression to a local variable:

varDecl(hasInitializer(ignoringExprWithCleanups(
                             ignoringParenImpCasts(integerLiteral()))))))

It's used 3 times.
