Attaching to a huge amount of fentry probes isn't currently possible due to the kernel's performance as you said. It is something that users want to do and should be...

Addressed most of the comments. Still need to add tests for multiple for-loops and fix the nested for-loop bug.

Fixed a lifetime bug I'd introduced for tuple elements: in `CodegenLLVM::visit(Tuple &tuple)` I'm now extending the lifetime of all tuple elements until the end of the function with: ``` scoped_dels.emplace_back(std::move(accept(elem)));...

A lot of the error messages I'm testing for in this PR appear to have regressed: #3063
