Before #52415 we could do multiple rounds of inlining on IR that had already been inlined, but this was no longer possible. By removing the assertion that was introduced in #52415, this commit makes it possible to do multi-inlining once more. Note that to fully solve this, though, we need to enhance `ir_inline_linetable!` so it can add new linetables to an inner linetable that's already been inlined. This commit notes that enhancement as something we need to do later, leaving it with a TODO comment.

I'll merge this to fix downstream packages that are relying on this being possible. It shouldn't affect backtrace correctness on master, though I'm imagining it might in the multiple inlining case, so it'll be good to address the todo. |
