    Refactor integer hashing function names

    We now clearly differentiate between:
    - unseeded hash for 32-bit integers
    - unseeded hash for 64-bit integers
    - seeded hash for 32-bit integers
    - seeded hash for strings

I swear I didn't plan this when I chose my github/twitter user name :)

@hashseed can you confirm this is already on master?

[hashseed]

This is not yet on master, since the last in this series of commits landed just a week ago in upstream V8. Should I float this on master as well?

[mcollina]

Yes definitely. This should be included in 11 (#23230).

[richardlau]

'v8_embedder_string' in common.gypi should be bumped.

[hashseed]

'v8_embedder_string' in common.gypi should be bumped.

Thanks. Done.

Yes definitely. This should be included in 11 (#23230).

There you go: #23264

[ofrobots]

LGTM w/ minor nit: the commit abstract can be shortened to the preferred guidelines. I suggest something like: deps: V8: cherry-pick 64-bit hash seed commits. This can happen at landing time, and the second commit squashed at that time.

[hashseed]

Squashed and reworded the commit message.
