[PATCH] D69947: [ThinLTO] Simplify attribute propagation

[Teresa Johnson via Phabricator via llvm-commits]

tejohnson added a comment.

Given the write only bug that popped up with the earlier patch, I'm wondering if this is safe. I.e. we must import a global variable if we have marked it as write only, so if we don't import it later (because it fails one of the legality checks in canImportGlobalVar), then we can end up in trouble.
