Auto merge of #55982 - alexcrichton:panic-extern-abort, r=zackmdavis
rustc: Switch `extern` functions to abort by default on panic This was intended to land way back in 1.24, but it was backed out due to breakage which has long since been fixed. An unstable `#[unwind]` attribute can be used to tweak the behavior here, but this is currently simply switching rustc's internal default to abort-by-default if an `extern` function panics, making our codegen sound primarily (as currently you can produce UB with safe code) Closes #52652
