[PATCH] D51329: [Attribute/Diagnostics] Print macro if definition is an attribute declaration

[Martin Storsjö via Phabricator via cfe-commits]

mstorsjo added a comment.

This caused a regression when including mingw-w64 headers (in a case where they happen to include redundant/duplicate attribute specifications), triggering asserts. See https://bugs.llvm.org/show_bug.cgi?id=41852 for details.
