This small series basically fix an outdated hexagon slot rule for
instruction hintjr and makes the decode machinery more resilient against
any possible outdated slot constraints in the future.

Matheus Tavares Bernardino (2):
  Hexagon (iclass): update J4_hintjumpr slot constraints
  Hexagon (decode): look for pkts with multiple insns at the same slot
