See Note [DCmmGroup vs CmmGroup or: Deterministic Info Tables] and Note [Object determinism]
cmm: Back LabelMap with UDFM
Use a deterministic unique map to back the implementation of `LabelMap`.
This is necessary towards the goal of object code determinism in #12935.
Our intended solution requires renaming uniques in a deterministic
order (which will be the order in which they were created), but storing
them label map makes us lose this order. Backing it with a UDFM fixes
this issue.
Introduce back LabelMap non deterministic
Use NonDeterministic Label map in multiple passes
(TODO: More could be available. Look through Det LabelMap uses again)
Use NonDet for CFG
More NonDet
More explicit
Introduce DCmmDecl, start
Removing more maps
