   encoding is split over two fields, each in it's own instruction. They
   can occur in any order. So given a thumb form of long branch, and an
   offset, insert the offset into the thumb branch and return finished
   instruction.

   It takes two thumb instructions to encode the target address. Each has
   11 bits to invest. The upper 11 bits are stored in one (identified by
   H-0.. see below), the lower 11 bits are stored in the other (identified
   by H-1).

   Combine together and shifted left by 1 (it's a half word address) and
   there you have it.

   Op: 1111 = F,
   H-0, upper address-0 = 000
   Op: 1111 = F,
   H-1, lower address-0 = 800

   They can be ordered either way, but the arm tools I've seen always put
   the lower one first. It probably doesn't matter. krk@cygnus.com

   XXX:  Actually the order does matter.  The second instruction (H-1)
   moves the computed address into the PC, so it must be the second one
   in the sequence.  The problem, however is that whilst little endian code
   stores the instructions in HI then LOW order, big endian code does the
   reverse.  nickc@cygnus.com.  */
