The first patch of this series deals with NOPS with invalid SBO/SBZ
fields were being wrongfully translated to TEQ's.
The 26-bit versions of TEQ/TST/CMN/CMP are now marked UNPREDICTABLE for
ARM V6 and higher.
See the definition of UNPREDICTABLE instructions and instruction
definitions for TEQ/TST/CMN/CMP
in the ARM Architecture Reference Manual ARMv7-A and ARMv7-R edition,
reference ARM DDI0406C,
on infocenter.arm.com.
The second patch adds tests for the 26-bit versions of teq,tst,cmn,cmp,
that were no longer tested after the first patch.
