Don't sort opcodes; move all pseudo-ops to the beginning
We don't need to sort opcodes anymore, since we are using an O(1) hash and not binary search. Instead, sort them in the order they first appear in insns.dat; this lets us move all the pseudo-ops to a contiguous range at the start of the file, for more efficient handling. Change the functions that process pseudo-ops accordingly. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
