Rollup merge of #77693 - bugadani:issue-59352, r=oli-obk
Add test for #59352 Issue #59352 reported an optimization regression with rustc 1.32.0+. That regression could be tracked to a change that caused a function to miss the size limit of llvm's inlining, which results in an unreachable panicing branch being generated. Enabling mir inline solves the issue, but is currently only done for `mir-opt-level>=2`. This PR adds a test that can serve as a regression test for #59352, if/when mir inlining gets mature enough for opt-level 1, or some other optimization can remove the panic.
