Intrinsic functions (both asm and graph intrinsics) do not expect unboxed parameters in most cases. This change adds checks to verify that and avoid generating incorrect code silently, in case parameters become unboxed. Fixes https://github.com/dart-lang/sdk/issues/43819 Change-Id: I71c1499bf8232f241316ae6b3cdeb57dec18fbb5 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/168622 Reviewed-by: Martin Kustermann <kustermann@google.com> Reviewed-by: Aske Simon Christensen <askesc@google.com> Commit-Queue: Alexander Markov <alexmarkov@google.com>
