I used do do an exchange like this in Boston, now I do one like this in Dover NH. Not a cloverleaf, but a high-speed merge, with traffic coming from the right off a highway in a dedicated lane, traffic flowing fast in my travel direction.

I will usually ride a shoulder if there is one and it is not full of crap. As I approach this kind of intersection, I'll hug the fog line so that I am riding the dividing line between two lanes as traffic comes together.

Then it depends -- if it's like my former commute where there is not an immediate right turn for an on-ramp, I will signal to get right and do so when there's a break in the traffic. Drivers don't really want a cyclist in the middle of traffic, so once I make my intention clear, usually cars will allow a merge. On my current commute, the lane merging from the highway turns into a right turn only lane -- like a cloverleaf situation -- so I will stay in the travel lane, either right on the lane divider or in the right travel track of the right-most lane going straight through.

My generic term for street situations like this is "meat-grinder."
