Fixes the reported errors on: https://github.com/llvm/llvm-project/pull/87379 A previous patch updated the bitcode reading for debug intrinsics/records to not perform the expensive debug info format conversion from records to intrinsics in cases where no records were present, but the patch did not actually track when debug labels had been seen, resulting in errors when parsing bitcode where functions contained debug label records but no other debug records. This patch fixes that case and adds a test for it.
