Without this patch, clang will not wrap in an ElaboratedType node types written without a keyword and nested name qualifier, which goes against the intent that we should produce an AST which retains enough details to recover how things are written. The lack of this sugar is incompatible with the intent of the type printer default policy, which is to print types as written, but to fall back and print them fully qualified when they are desugared. An ElaboratedTypeLoc without keyword / NNS uses no storage by itself, but still requires pointer alignment due to pre-existing bug in the TypeLoc buffer handling.
