This doesn't reduce the quality of tests, because the flags are still
printed for declarations themselves. We only omit them in references.
However, this makes the tests more compatible with non-JVM backends
(see KT-58605), because flags of referenced stdlib declarations may
differ among target platforms.
See the relevant test at t/
estData/codegen/box/sam/contravariantIntersectionType.kt
After the previous commit, when generating a call for `doOnSuccess {}`,
we have a SAM type with removed projection Consumer<Any?>, while
real function type of the lambda is a bit different
(Function1<ConcreteType & ConcreteType2>).
While for me, that looks questionable, but in K1 it was effectively
resolved via the same implicit cast that on JVM is generated to an
INVOKEDYNAMIC that wraps initial function-typed value.
