Note [Renaming uniques deterministically]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+TODO:::::::
To produce deterministic object code, we alpha-rename all Uniques to deterministic uniques before Cmm linting.
From here on out, the backend code generation can't use (non-deterministic) Uniques, or risk producing non-deterministic code.
For example, the fix-up action in the ASM NCG should use determinist names for potential new blocks it has to create.
