[PATCH] D48722: [ASTImporter] Update isUsed flag at Decl import.

Originally this change was made after the patch in https://reviews.llvm.org/D47632 was done. It is here back-ported to the state before it. I like the idea of integrating this change into https://reviews.llvm.org/D47632. (This is a new functionality: Attributes are updated when something is found to be already imported, in contrast to copy of the attributes when a new object is created.)
