H.J. Lu bc31405ebb x86-64: Properly encode and decode movsxd 
movsxd is a 64-bit only instruction.  It supports both 16-bit and 32-bit
destination registers.  Its AT&T mnemonic is movslq which only supports
64-bit destination register.  There is also a discrepancy between AMD64
and Intel64 on movsxd with 16-bit destination register.  AMD64 supports
32-bit source operand and Intel64 supports 16-bit source operand.

This patch updates movsxd encoding and decoding to alow 16-bit and 32-bit
destination registers.  It also handles movsxd with 16-bit destination
register for AMD64 and Intel 64.
