Issue Description:
After upgrading to swift 5.6, a simple Swift package wrapping some C code now crashes during SIL generation. This worked correctly in 5.5 and so should be considered a regression.
I have attached project of identical structure to demonstrate.
The C Sources are shared across many projects/platforms and are dropped in, so may change contents for a build but the structure is fixed. SPM seems the only way to isolate that code.
