Should we actually assert on something here?

Forgot to remove that test when I was writing this. I don't think it serves much of a purpose.

That's a beefy change, fingers crossed🤞
This makes debug id injection into JS files precise.
"use strict";
statement.magic-string
to insert the debug id code snippet at the injection point and append the//# debugId
comment.magic-string
give us a sourcemap that maps between the injected and original file. This is really only relevant for the code snippet, the comment is just appended and shouldn't affect mappings anyway.The sourcemap obtained in (3) is then used to rewrite the original sourcemap using
SourceMap::adjust_mappings
.This also minorly refactors
fixup_js_file_end
.
