d6a041b8f9 Remove some more uses of subgraphs and more cleanup of the graph builder. 
Do not use subgraphs to implement the translation of simple branching
control flow, for the function body entry, or for labeled blocks.

Combine all the loop construction functions into a single one.

Resolve a possible problem with duplicate AST IDs used both for joined loop
break blocks, the normal loop exit, and for their common successor, by never
introducing the extra (successor) block and instead making the normal loop
exit a predecessor of the break join block.  There is a similar issue with
joined continue blocks.

Remove a (never needed) two-element zone list per each time we replace one
hydrogen value with another.

043a876e93 Translate loops without using subgraphs. 
Build all loop graphs without using class HSubgraph.  This also eliminates a
silly goto for the update expression of a for loop.

Support for peeling loops is removed because it's currently untested.

ef06ab5f3e Enable optimizing JSFunctions that are in new-space. 
It avoids strange performance behavior where hot functions do not
