Because branch relaxation needs to factor in if branches target a block in the same section or a different one, it needs to run after the Basic Block Sections / Machine Function Splitting passes. Because Jump table compression relies on block offsets remaining fixed after the table is compressed, we must also move the JT compression pass. The only tests affected are ones enforcing just the ordering and the a few that have basic block ids changed because RenumberBlocks hasn't run yet.
