04e7f96dd8 Auto merge of #69227 - Marwes:buffer_stderr, r=varkor 
perf: Buffer stderr when writing json errors/warnings

Since `stderr` is unbuffered, writing out json messages actually take up
about ~10%/0.1s of the runtime of the `inflate` benchmark as it generates a fair number of warnings.

Rollup merge of #69563 - andre-richter:fix_no_std_match, r=Mark-Simulacrum 
Fix no_std detection for target triples

The current check for wether a target is no_std or not is matching for the string `-none-` in a target triple. This doesn't work for triples that end in `-none`, like `aarch64-unknown-none`.

Fix this by matching for `-none` instead.

I checked for all the current target triples containing `none`, and this should not generate any false positives.

This fixes an issue encountered in https://github.com/rust-lang/rust/pull/68334

Use assert_ne in hash tests

The hash tests were written before the assert_ne macro was added to the standard library. The assert_ne macro provides better output in case of a failure.
