adapt tests/codegen/vec-shrink-panik for LLVM 17
After https://github.com/llvm/llvm-project/commit/0d4a709bb876824a0afa5f86e138e8ffdcaf7661 LLVM now doesn't generate references to panic_cannot_unwind: @nikic: https://rust-lang.zulipchat.com/#narrow/stream/187780-t-compiler.2Fwg-llvm/topic/a.20couple.20codegen.20test.20failures.20after.20llvm.200d4a709bb876824a/near/342664944 >Okay, so LLVM now realizes that double panic is not possible, so that's fine.
