MIPS16/opcodes: Fix and clarify MIPS16e commentary
Correct the note about JALRC/JRC being compact jumps rather than
branches, and add a reference from where the remaining MIPS16e additions
live and the jumps used to be too, complementing commit ceb94aa50d68
("Update insn_mo when converting to a MIPS16e compact jump"),
<https://sourceware.org/ml/binutils/2011-06/msg00369.html>.

compact jumps.
