[PATCH] D32372: Arrays of unknown bound in constant expressions

[Robert Haberlach via Phabricator via cfe-commits]

Arcoth added a comment.

Updated `SubobjectDesignator` to hold `MostDerivedIsAnUnsizedArray` instead of `FirstEntryIsAnUnsizedArray`. Consequently, we cannot know whether the first element is an unsized array; please see line 7352 in particular, where the check for `isMostDerivedAnUnsizedArray`had to be removed (is this fine? All regression tests pass.)
