dis: Allow decoding of 66 (%cs:) segment override even when amd64
This is now generated by GCC 4 as part of an extended multi-byte nop as
variable-length executable padding of the form:
66 66 66 2e 0f 1f 84
Where the number of 66 (address size) prefixes varies according to the
amount of pad required.
