Silence a misleading warning with some comprehensions

When compiling comprehensions with generators which are foldable to
'true', a misleading warning is emitted by sys_core_fold because a
clause resulting from the compilation of the comprehension to Core
Erlang is not marked as generated by the compiler.

An example of such a comprehension is [ true || true ].
