Auto merge of #31116 - bluss:expect-out-cold, r=alexcrichton

Use cold functions for panic formatting Option::expect, Result::unwrap, expect

These methods are marked inline, but insert a big chunk of formatting
code, as well as other error path related code, such as
deallocating a std::io::Error if you have one.

We can explicitly separate out that code path into a function that is
never inline, since the panicking case should always be rare.
