Unrolled build for rust-lang#138294

Rollup merge of rust-lang#138294 - paulmenage:test-panic-unwind, r=bjorn3

Mark some std tests as requiring `panic = "unwind"`

This allows these test modules to pass on builds/targets without unwinding support, where `panic = "abort"` - the ignored tests are for functionality that's not supported on those targets.
