All statements that involve conditions can now hold on to a separate condition declaration (a VarDecl), and will use a DeclRefExpr referring to that VarDecl for the condition expression. ForStmts now have such a VarDecl (I'd missed those in previous commits). Also, since this change reworks the Action interface for if/while/switch/for, use FullExprArg for the full expressions in those expressions, to ensure that we're emitting Note that we are (still) not generating the right cleanups for condition variables in for statements. That will be a follow-on commit. llvm-svn: 89817
