[PATCH] D143645: [llvm] Fix MCSubtargetInfo::checkFeatures to handle unknown features correctly

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

Is this new behavior visible through some existing non-test callers of `MCSubtargetInfo::checkFeatures`? Could that be tested using a lit-style test to demonstrate that this behavior is desirable/correct at that scope, beyond the narrower unit test?
