Reliably mark the loop variable declaration in a range for as having an invalid initializer if anything goes wrong building the initializer. We previously based this determination on whether an error was emitted, which is not a reliable signal due to error suppression (during error recovery etc). Also, properly mark the variable as having initializer errors rather than simply marking it invalid. This is necessary to mark any structured bindings as invalid too. This generalizes the previous fix in 936ec89e91e2dda8b6110b1fd1f9920509d7a17b.
