Rollup merge of #32699 - bluss:slice-memcmp, r=alexcrichton
Specialize equality for [T] and comparison for [u8] to use memcmp when possible Specialize equality for [T] and comparison for [u8] to use memcmp when possible Where T is a type that can be compared for equality bytewise, we can use memcmp. We can also use memcmp for PartialOrd, Ord for [u8]. Use specialization to call memcmp in PartialEq for slices for certain element types. This PR does not change the user visible API since the implementation uses an intermediate trait. See commit messages for more information. The memcmp signature was changed from `*const i8` to `*const u8` which is in line with how the memcmp function is defined in C (taking const void * arguments, interpreting the values as unsigned bytes for purposes of the comparison).
