target-alpha: fix cmpbge instruction

The cmpbge instruction should compare all 8 bytes of one 64-bit value with
another.  However, we were looping with a < 7 condition which was skipping
the top byte.  So if we were doing a compare where the top byte was
important, we could get the wrong result (this notably breaks the strlen()
function with certain sized strings).
