Since [r291545](http://llvm.org/viewvc/llvm-project?view=revision&revision=291546) `invalid-opencl-version-metadata{1,2,3}.ll` and `runtime-metadata.ll` tests fail. The bug is tracked as [31610](https://bugs.llvm.org//show_bug.cgi?id=31610) on LLVM's Bugzilla. Any help finding the root cause will be greatly appreciated.
