Added target to produce llvm ir for JavaScriptCore.  WIP for C++ inlining.

Does not handle stale Runtime.symtbl 

The worst thing that can occur is that the symbol table will contain symbols which no longer exist.  At the moment this will have no effect on runtime since Runtime.symtbl is not used.
When Runtime.symtbl is being used (patch forthcoming), either the symbols will never be accessed (since they don't exist exposed in runtime, they can't be called by js code), or when they are accessed the FTL code will simply not inline them after catching an error.
