These date back to when the non-intrinsic format of variable locations was still being tested and was behind a compile-time flag, so not all builds / bots would correctly run them. The solution at the time, to get at least some test coverage, was to have tests opt-in to non-intrinsic debug-info if it was built into LLVM. Nowadays, non-intrinsic format is the default and has been on for more than a year, there's no need for this flag to exist. (I've downgraded the flag from "try" to explicitly requesting non-intrinsic format in some places, so that we can deal with tests that are explicitly about non-intrinsic format in their own commit).
