James Molloy 2629049216 [SimplifyCFG] Harden up the profitability heuristic for block splitting during sinking ...

Exposed by PR30244, we will split a block currently if we think we can sink at least one instruction. However this isn't right - the reason we split predecessors is so that we can sink instructions that otherwise couldn't be sunk because it isn't safe to do so - stores, for example.

So, change the heuristic to only split if it thinks it can sink at least one non-speculatable instruction.

Should fix PR30244.
