tcg/POWER9: NOOP the cp_abort instruction 

The cp_abort instruction is used to remove the state of an in progress
copy paste sequence. POWER9 compilers add this in various places, such
as context switches which causes illegal instruction signals since we
don't yet implement this instruction.

Given there is no implementation of the copy paste facility and that we
don't claim to support it, we can just noop this instruction.
