Instead of eagerly populating the stack trace with a textual representation of every call frame, just store the raw source code range (code, start offset, end offset). From that, we can generate the full rich backtrace when requested, and save ourselves the trouble otherwise. This makes test-wasm take ~7 seconds on my machine instead of ~60. :^)
