I'm totally fine with having one big task. Some rationale on why things ended
up this way: we had two tasks for supporting these instructions in ISACaller, I
just made two symmetrical tasks for binutils.

As for the payment, I'm not sure what sum to put. Based on my experience with
1068 and similar tasks, there might be issues on openpower-isa side (be it
codegen, new operands or states, etc.). Even 700 EUR for 1147 was an arbitrary
choice based on the fact that 1119 (which gave birth to 1148) had 300 EUR...
