[PATCH] NEON instructions were erroneously decoded from certain invalid encodings

[Artyom Skrobov]

Tim, unfortunately such a test is impossible: for all instructions in the
v8NEON32 range, the aliasing encodings are defined as valid instructions, so
these definitions are checked before masking the encoding and matching it
against DecoderTablev8NEON32.

It's pure luck that for sha256h one of the aliasing encodings were
undefined, which gave this error away.

OK to commit the test as it is?

Hi Artyom,

> OK to commit this fix?

Could you add a test using an instruction that would be in the
v8NEON32 space too? I'm happy for you to commit with that change, and
I'll take a last look at it in post-commit.

Cheers.

Tim.
