Reviewers: fschneider, Vitaly Repeshko, Description: Refactor construction of switch statements to avoid subgraphs.
Refactor construction of switch statements so it doesn't use class HSubgraph. There are also a few improvements. We do not use an auxiliary list of comparisons because they're embedded as a linked list in the graph under construction. We share a common break block for all breaks from the same switch. We do not insert empty blocks unless necessary to maintain edge-split form. There is also a bug fix. The entry to a clause body is a potential join and must have a join ID set, otherwise deoptimization within the body can go to an unpredictable place in the unoptimized code.
