When visiting an attr/type that is NoAlias, the created
`InProgressAliasInfo` was not getting its `canBeDeferred` and `isType`
fields set. Not setting `canBeDeferred` when it should be true breaks
the assumption that all nested elements are also false. This will cause
problems when at a later point the attr/type needs to be converted by
`markAliasNonDeferrable`, as recursion will stop when a
`canBeDeferred=false` attr/type is reached, leaving its nested elements
not flipped. This causes nested elements to be printed later in the
textual IR and cannot be parsed back in.
