To properly recognize control-flow constructs in sets, the constant
evaluator needs to get un-desugared set literals. This commit skips the
desugaring of const set literals if the constant evaluator is enabled
and adds a similar desugaring in the constant evaluator.
Doing the desugaring in the constant evaluator (which can be called
independently of Fasta) necessitates that dart:collection is indexed
in CoreTypes. We can remove this indexing again when the VM gains
native support for set constants.
