Compiler crash when building WebAssembly for debug - Assertion !f->isGeneric() failed

[CallumTodd7]

Description

Apple's swift-for-wasm-examples works in the stated release mode, but the compiler crashes when building for debug mode.

Reproduction

1. Clone Apple's swift-for-wasm-examples
2. Run swift build --triple wasm32-unknown-none-wasm -c debug --product swift- audio

Stack dump

Expected behavior

Building for debug mode shouldn't cause a crash.

Environment

Swift version 6.0-dev (LLVM 320c9b9b7bd4fd8, Swift 49dd95f)
Target: aarch64-unknown-linux-gnu

Docker image: swiftlang/swift:nightly-jammy
.swift_tag: swift-DEVELOPMENT-SNAPSHOT-2024-04-25-a
