Consider changing `Consume` to not hold onto references for very long

JIT: update block weight for uncond to cond flow opt

This optimization duplicates code and flow in a BBJ_COND successor into one of its preds; as a result the weight of the successor should decrease. Fixes some issues seen with...

11

If these don't match then benchmark times will be either under or over estimated. Context https://github.com/dotnet/runtime/issues/86033#issuecomment-1546306621 This is the "good" case where the jit isn't messing up the workload invoke...
