Note [ModuleEnv performance and determinism]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To prevent accidental reintroduction of nondeterminism the Ord instance
for Module was changed to not depend on Unique ordering and to use the
lexicographic order. This is potentially expensive, but when measured
there was no difference in performance.

To be on the safe side and not pessimize ModuleEnv uses nondeterministic
ordering on Module and normalizes by doing the lexicographic sort when
turning the env to a list.
See Note [Unique Determinism] for more information about the source of
nondeterminismand and Note [Deterministic UniqFM] for explanation of why
it matters for maps.
