Re-enable parallel frontend tests for post-monomorphization errors

xmakro · xmakro · commit c9c1d536149e · 2026-06-03T08:47:59.000-07:00
These were marked ignore-parallel-frontend because the spurious instantiation
note made their output nondeterministic under -Zthreads. With that fixed they
pass reliably. Replace the directive with a blank line rather than deleting it,
so the following line numbers stay the same and the expected output is unchanged.
