[PATCH][GAS][AArch64] Add dot product support for AArch64 to binutils [Patch (1/2)]

[Tamar Christina]

Hi All,

This patch adds assembler and disassembler support for new Dot Product
instructions to AArch64.
    
The support can be enabled through the new "+dotprod" extension.
    
"+dotprod" extension is an optional extension to ARMv8.2-A onwards.

Ok for Trunk?

Ps. I do not have commit access so if OK can someone apply for me?

Thanks,
Tamar
