Running swift build or repl on a package that imports Foundation from Swift 6 downloaded toolchain will crash

[marcprux]

Description

Installing the Swift 6.0 toolchain from https://www.swift.org/download/ on an ARM macOS 15 host with Xcode 16 installed attempting to build a package that uses Foundation will crash (see "Reproduction" for full output).

% ~/Library/Developer/Toolchains/swift-6.0-RELEASE.xctoolchain/usr/bin/swift run

Building for debugging...
error: emit-module command failed due to signal 6 (use -v to see invocation)
Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.

Also, running swift repl, attempting to import Foundation will fail with many errors after 2 minutes. Some choice examples of the errors are:

objc[79208]: Class _TtCs25CheckedContinuationCanary is implemented in both /usr/lib/swift/libswift_Concurrency.dylib (0x277303120) and /Users/marc/Library/Developer/Toolchains/swift-6.0-RELEASE.xctoolchain/usr/lib/swift/macosx/libswift_Concurrency.dylib (0x100461848). One of the two will be used. Which one is undefined.
arm64e-apple-macos.swiftinterface:2:1: fatal error encountered while reading from module '_errno'; please submit a bug report (https://swift.org/contributing/#reporting-bugs)
arm64e-apple-macos.swiftinterface:5:8: failed to build module 'Darwin' for importation due to the errors above; the textual interface may be broken by project issues or a compiler bug

Running import Foundation a second time appears to work, and some types are available (like URLSession), but other types (like URL) are not.

This sounds similar to #58658 and swiftlang/swift-package-manager#5467
