Rollup merge of rust-lang#95072 - tromey:parallel-debug-tests, r=tmiasko

Dylan-DPC · web-flow · commit 69e8ffc5856c · 2022-03-18T19:28:47.000+01:00
Re-enable parallel debuginfo tests Debuginfo tests are serialized due to some older version of LLDB. However, that comment was last touched in 2014, so presumably these older versions are long since obsolete. Partially fixes bug rust-lang#72719.
