…r=alexcrichton Fix a race condition caused by concurrently executed codegen unit tests. This hopefully fixes issue #33315. This short-term solution just makes sure that every test uses its own directory so they can't get into conflict with each other. As a more long-term solution, I'd probably prefer to make the partitioning scheme specifiable via `-Ccodegen-units` (e.g. like `-Ccodegen-units=per-module`) so that we don't have to rely on `-Zincremental` in these test cases. r? @alexcrichton

Been seeing a bunch of these recently, gonna link up a few PRs to this to track them all here. @michaelwoerister here thought that this is due to the additions in #33171 which seems plausible to me as a bunch of compilations are now sharing the same incremental directory
