Simon Pilgrim 1cc5712763 [X86][XOP] Support for VPPERM 2-input shuffle mask decoding
This patch adds support for decoding XOP VPPERM instruction when it represents a basic shuffle.

The mask decoding required the existing MCInstrLowering code to be updated to support binary shuffles - the implementation now matches what is done in X86InstrComments.cpp.

Simon Pilgrim 476170384f [X86] Tidied up shuffle decode function doxygen descriptions
As discussed on D18441 - auto brief is used so we don't need /brief, we don't need to include the function name and added some missing descriptions.
