Fixed by r273314. Sorry for the inconvenience. I did not put a proper
back-reference to this issue in the change log.

The issue seems to be that jump pass tail merges two blocks ending in indirect
calls to  mit_tsi.isra.2 and emit_branch.isra.5 ignoring the REG_CALL_DECL
notes attached to them which messes up the resource info later on for delay
slot filler.
