Missing diagnostic about missing dependency #6607

Description
Check out the missing-dependency-diagnostic tag from the https://github.com/val-lang/val project, follow the setup instructions if you haven't already, and do swift -vv test. You will get link errors. It turns out that this change is missing, but SPM / the swift compiler doesn't tell me about it:
diff --git a/Package.swift b/Package.swift
index fa1d158f..3203e9c4 100644

+++ b/Package.swift

dependencies: [
"Utils",
.product(name: "LLVM", package: "Swifty-LLVM"),
+ .product(name: "Collections", package: "swift-collections"),
],
swiftSettings: allTargetsSwiftSettings),
This is a big problem because often these missing dependencies don't result in link errors (like the state of that project at 5806c04fcb2b9). The project builds/runs/tests but who knows what misbehavior may have resulted from the mis-specification of Package.swift. If my tests fail, is it because of some unspecified dependency? Can't tell.
