[PATCH] D82820: [InstCombine] Fix mismatched attribute lists for combined calls

[Gui Andrade via Phabricator via llvm-commits]

guiand added a comment.

I was discussing with @eugenis about this and he suggested that it's reasonable not to copy any call-inst attributes when simplifying LibCalls. Specifically because you run into these messy questions of how reasonable it is to blindly apply attributes as a caller. Since LibCalls have their own inherent attribute lists which get applied upon creating a `Function` instance for them, it seems like we shouldn't impose any further attributes.
