gcc is smart enough to use an even register for 64bits operations, and provide
a way to access the first and the second words, so use that instead of
hardcoding registers.
This adds support for CAS_64{_VALUE}, CAS_PTR_2{_VALUE},
LOAD_64, STORE_64 and other primitives built on universal
CAS primitive.

Besides implementing Thumb 2 supports, this fixes incorrect usage of
"cmp" where "cmpeq" was meant.
