Issue Description:

Compiling attached project causes error: Illegal instruction: 4 (in target 'InterposeKit' from project 'InterposeKit')

The changes that moved the project from compiling to triggering the crash are here:

https://github.com/steipete/InterposeKit/pull/15/commits/1fb6c6c7e78cf7b6ee2ca02d8c19405afb8199eb

When I use the latest master toolchain I get an Abort trap: 6 instead with better diagnostics

1. Apple Swift version 5.3-dev (LLVM 84c026a1b9, Swift 6bda828a7e)

2. While evaluating request ExecuteSILPipelineRequest(Run pipelines { Mandatory Combines, Serialization, Rest of Onone } on SIL for InterposeKit.InterposeKit)

3. While running pass #260 SILModuleTransform "SerializeSILPass".

4. While serializing type '@convention(c) (UnsafePointer\<objc_super>, Selector, va_list) -> Unmanaged\<AnyObject>'

5. While staging a serialized reference to PointerType 0x7fa26d0a02f0 'id *⭐(const struct objcsuper *, SEL *, struct \_va_list_tag)'
