[Julian Brown via llvm-branch-commits]

https://github.com/jtb20 created https://github.com/llvm/llvm-project/pull/216328

Adds a regression test for a taskgraph deadlock that occurred when
non-replayable tasks were encountered during taskgraph recording --
not lexically nested within the taskgraph construct.
