nfc: refactor Backtracing/Crash.swift
This test fused both the CHECK directives and the source code into one file, and is sensitive to the line numbers that source code appears on in that file. Thus, any attempts to add new lines to this test would break it. This refactoring moves the source code to a separate file so its line numbers stay stable.
