Yeah, but IDK if it causes an ICE in CTFE and therefore deserves tainting like this. |

Rollup merge of #142983 - compiler-errors:taint-invalid-call-abi, r=workingjubilee Taint body on invalid call ABI Fixes #142969 I'm not certain if there are any other paths that should be tainted, but they would operate similarly. Perhaps pointer coercion. Introduces `extern "rust-invalid"` for testing purposes. r? ```@workingjubilee``` or ```@oli-obk``` (or anyone)
