These should correspond to the instructions original source as per: 'ARM Architecture Reference Manual ARMv7-A and ARMv7-R edition' found at: http://infocenter.arm.com/help/topic/com.arm.doc.ddi0406c/index.html

There are three exceptions here, CLREX, LDREXB and LDREXD. These instructions should be assigned attributes to represent ARMv7 and not ARMv6T2. The tests were left describing the current behavior, to detect any change, potentially pending a fix.
