RFR: 8267531: [x86] Assembler::andb(Address, Register) encoding is incorrect

[Aleksey Shipilev]

See the bug report to see the way we arrived here. I looked through the [breakage changeset](https://github.com/openjdk/jdk/commit/de784312c340b4a4f4c4d11854bfbe9e9e826ea3), and I think that is the only "*b" case that is missing.

Attention @JohnTortugo.

Additional testing:
 - [x] Failing fuzzer test (now passes)
 - [ ] Linux x86_64 fastdebug `tier1`
