objtool: Resync objtool's instruction decoder source code copy with the kernel's latest version 

This fixes the following warning:

  warning: objtool: x86 instruction decoder differs from kernel

Note that there are cleanups queued up for v4.16 that will make this
warning more informative and will make the syncing easier as well.
