[PATCH] D36575: [ARM] Assembler support for the ARMv8.2a dot product instructions

[Sjoerd Meijer via Phabricator via llvm-commits]

Added the disassembler tests.

Note that the AArch32 instructions were added to the an instruction encoding space that has been reclaimed from what was originally allocated for the unused “Coprocessor 13”.
That's why I created a DecoderNamespace CoProc and assigned the coprocessor isntructions to it, otherwise the dot product instructions would get disassembled to coprocessor instructions.
