Add support for the lbarx, lharx, stbcx and sthcs instructions.

One of the expect files was missing.  Also found that there 
was a bug in the stq, stqcx, lq and lqarx instructions for LE.
The VEX commit for the instruction fix was 3138.

This commit updates the expect files for the corrected instructions
and adds the missing expect files.

The bugzilla for the orginal issue of the missing instructions
is 346324.
