Jonas Jensen 6ee3def942 C++ IR: Speed up getInstructionOperand ...

The `SSAConstruction::Cached::getInstructionOperand` predicate took
1m27s on a postgres snapshot before this change and was the slowest
predicate in SSAIR. It now takes 4.5s.

The slowdown was caused by its use of
`getUnmodeledDefinitionInstruction`, which got inlined into a place
where join orderer had little choice but to join the `MkInstruction`
relation with itself, creating a large intermediate relation.

I've added `pragma[noinline]` to `getUnmodeledDefinitionInstruction` and
also to similar predicates that are likely to cause the same problem in
the future.
