With this, debugging LLInt code will be easier.  LLInt code will no longer all be at an offset from vmEntryToJavaScript.  They will instead be broken up into different sections under human readable labels.

Secondly, crash traces of LLInt crashes will now be able to tell us give us the nearest label, as opposed to everything being an offset from vmEntryToJavaScript.
