auto merge of #12098 : kballard/rust/from_utf8_lossy_tweak, r=huonw
MaybeOwned allows from_utf8_lossy to avoid allocation if there are no invalid bytes in the input. Before: ``` test str::bench::from_utf8_lossy_100_ascii ... bench: 183 ns/iter (+/- 5) test str::bench::from_utf8_lossy_100_invalid ... bench: 341 ns/iter (+/- 15) test str::bench::from_utf8_lossy_100_multibyte ... bench: 227 ns/iter (+/- 13) test str::bench::from_utf8_lossy_invalid ... bench: 102 ns/iter (+/- 4) test str::bench::is_utf8_100_ascii ... bench: 2 ns/iter (+/- 0) test str::bench::is_utf8_100_multibyte ... bench: 2 ns/iter (+/- 0) ``` Now: ``` test str::bench::from_utf8_lossy_100_ascii ... bench: 96 ns/iter (+/- 4) test str::bench::from_utf8_lossy_100_invalid ... bench: 318 ns/iter (+/- 10) test str::bench::from_utf8_lossy_100_multibyte ... bench: 105 ns/iter (+/- 2) test str::bench::from_utf8_lossy_invalid ... bench: 105 ns/iter (+/- 2) test str::bench::is_utf8_100_ascii ... bench: 2 ns/iter (+/- 0) test str::bench::is_utf8_100_multibyte ... bench: 2 ns/iter (+/- 0) ```
