Rollup merge of #69814 - jonas-schievink:gen-ret-unw, r=Zoxc
Smaller and more correct generator codegen This removes unnecessary panicking branches in the resume function when the generator can not return or unwind, respectively. Closes https://github.com/rust-lang/rust/issues/66100 It also addresses the correctness concerns wrt poisoning on unwind. These are not currently a soundness issue because any operation *inside* a generator that could possibly unwind will result in a cleanup path for dropping it, ultimately reaching a `Resume` terminator, which we already handled correctly. Future MIR optimizations might optimize that out, though. r? @Zoxc
