fcedaa5714efab8738446fa21620b827a40a3458 by Derek Mauro <dmauro@google.com>:
Uses Wyhash in the implementation of absl::Hash for hashing sequences
of more than 16 bytes on some platforms.
Due to the per-process randomization of the seed used by absl::Hash, users
should not notice this change, other than possibly getting better performance.
This change only affects platforms where absl::uint128 is implemented
with an intrinsic (and where sizeof(size_t)==8) since Wyhash relies on
fast 128-bit multiplication for speed.

Minimize strings_internal::StringConstant further, by removing the need for the compiler to instantiate a compile-time class function.
