Bug #52452 notes some debuginfo test regressions when moving to gdb 8.1. This series will also cause versions of gdb before 8.2 to fail when a recent LLVM is used -- DW_TAG_variant_part support was not added until 8.2. This patch updates one of the builders to a later version of Ubuntu, which comes with gdb 8.2. It updates the relevant tests to require both a new-enough LLVM and a new-enough gdb; the subsequent patch arranges to continue testing the fallback mode. The "gdbg" results are removed from these tests because the tests now require a rust-enabled gdb. If you read closely, you'll see that some of the lldb results in this patch still look a bit strange. This will be addressed in a subsequent patch; I believe the fix is to disable the Python pretty-printers when lldb is rust-enabled.
