7d0861b20256ff623eb841b7e1a0c886f82b0361 more bits for shader program hash
gm/lumafilter is drawing wrong for me with SkVMBlitter,
but only when I enable its cache. I thought it must be
a collision between program fingerprints, but on further
inspection that doesn't seem to be the case, even 32-bit.
But now that I've done this, might as well keep it.
Even if p(collision) is small, p^2 is smaller.
Other small cleanups to what we hash and how:
- don't include derived fields in Instruction equality and hashing
- use SkOpts::hash() instead of manual std::hash/xor hack
Small struct layout changes to keep everything dense.
