LLDB doesn't import C-dependent package unless debug symbols are present

Describe the bug
When using a package on Swift-Colab with the build flags -c release -Xswiftc -Onone, there is an inconsistent and worsening problem with loading Swift modules into LLDB. You have to restart the runtime and re-install the packages, sometimes multiple times, to make it load. This isn't that bad of an issue, because each re-install utilizes cached build products and takes only 1 second. But it is a bug.
I suspect that this is not a fault of Swift-Colab, but rather a fault of the Swift compiler, SwiftPM, or LLDB. Due to the bug's nature, it will be difficult to narrow down. Please read through conversation on philipturner/swift-colab#15 for the full details on this bug.
Environment (please complete the following information):
