Discussed this offline. This is simple mechanical patch following the same pattern as previous features and completes ACLE support for Armv9.6. The issue is likely caused by the number of options now crossing some threshold, a pathological case in the StringSwitch perhaps. Given the slowdown is small and unlikely to be caused by anything directly in this PR, it's worth backporting as this completes ACLE enablement for Armv9.6.
