auto merge of #13522 : seanmonstar/rust/sip, r=alexcrichton
work started from @gereeter's PR: https://github.com/mozilla/rust/pull/13114 but adjusted bits ``` before test hash::sip::tests::bench_u64 ... bench: 34 ns/iter (+/- 0) test hash::sip::tests::bench_str_under_8_bytes ... bench: 37 ns/iter (+/- 1) test hash::sip::tests::bench_str_of_8_bytes ... bench: 43 ns/iter (+/- 1) test hash::sip::tests::bench_str_over_8_bytes ... bench: 50 ns/iter (+/- 1) test hash::sip::tests::bench_long_str ... bench: 613 ns/iter (+/- 14) test hash::sip::tests::bench_compound_1 ... bench: 114 ns/iter (+/- 11) after test hash::sip::tests::bench_u64 ... bench: 25 ns/iter (+/- 0) test hash::sip::tests::bench_str_under_8_bytes ... bench: 31 ns/iter (+/- 0) test hash::sip::tests::bench_str_of_8_bytes ... bench: 36 ns/iter (+/- 0) test hash::sip::tests::bench_str_over_8_bytes ... bench: 40 ns/iter (+/- 0) test hash::sip::tests::bench_long_str ... bench: 600 ns/iter (+/- 14) test hash::sip::tests::bench_compound_1 ... bench: 64 ns/iter (+/- 6) ``` Notably it seems smaller keys will hash faster. A long string doesn't see much gains, but compound cuts in half (once compound used a `int` and `u64`).
