4e97607d9a Use sse4.2 CRC32 instructions to hash when available. 
About 9x faster than Murmur3 for long inputs.

Most of this is a mechanical change from SkChecksum::Murmur3(...) to SkOpts::hash(...).

56da025020 Switch uses of SkChecksum::Compute to Murmur3. 
SkChecksum::Compute is a very, very poorly distributed hash function.
This replaces all remaining uses with Murmur3.

The only interesting stuff is in src/gpu.

c8d1dd48c0 SkTHash: hash from fnptr to functor type 
Passing &SkGoodHash to SkTHashMap and SkTHashSet doesn't guarantee that it's actually instantiated.  Using a functor does.

02f46cf878 Some usability ideas around SkTHash. 
- By default, use new SkGoodHash to hash keys, which is:
    * for 4 byte values, use SkChecksum::Mix,
    * for SkStrings, use SkChecksum::Murmur3 on the data,
    * for other structs, shallow hash the struct with Murmur3.
  - Expand SkChecksum::Murmur3 to support non-4-byte-aligned data.
  - Add const foreach() methods.
  - Have foreach() take a functor, which allows lambdas.
