Delete a comment that makes no sense to me. The statement that moving a CPE

before its reference is only supported on ARM has not been true for a while.
In fact, until recently, that was only supported for Thumb.  Besides that,
CPEs are always a multiple of 4 bytes in size, so inserting a CPE should have
no effect on Thumb alignment.
