Hey @kgyrtkirk can you please take another look here? Tests passed, had to
retriger.
Extended the backtracking logic to use the non-RS brach for the probe-MJ
logic -- this actually revealed several missed or wrong optimizations (updated
q outs).
Also extended the optimization logic to check if there a type Cast between
src and destination (as the types have to match in the probe case) and only use
it on the LLAP mode (probedecode's target).
