37bd114925 Update ObjectToString to Harmony-draft algorithm 
Updates Object.prototype.toString() to use algorithm described in harmony drafts.

Currently, the behaviour is essentially the same as ES262's version, however this changes when internal structures
such as Promise make use of symbolToStringTag (as they are supposed to, see v8:3241), and changes further once
Symbol.toStringTag is exposed publicly.

bc475b4a6b Add inlining for intrinsics. 
This issue is for discussion on how to proceed.

I think the implementation of ValueOf shows that directly creating the IR does not scale.

e4c6f9488e Implement graph trimming in ControlReducer. 
Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.

This CL is one half of the ControlReducer functionality, the other half
being branch folding.
