[PATCH] [ARMv8] SETEND is deprecated.

[Tim Northover]

  Hi Joey,

  I think it looks reasonable.

  > Is there a need for a proper solution to deprecated instructions in TableGen?

  How many are there? The ones I can think of at the moment are:
    + SETEND
    + SWP (deprecated v7?)
    + CP15 barriers
    + Weird IT restrictions

  Unless there are significantly more in a fairly regular pattern I suspect putting this in TableGen would be more complex than individual C++ code.

  Cheers.

  Tim.
