[PATCH 6/6] Wire up delayed typo correction to DiagnoseEmptyLookup and set up Sema::ActOnIdExpression to use the new functionality.

[Kaelyn Takata]

Among other things, this eliminates at least one redundant error case
and allows recovery in several cases where it wasn't possible before
(e.g. correcting a mistyped static_cast<>).
