DFG should optimize ResolveGlobal
https://bugs.webkit.org/show_bug.cgi?id=89617
Reviewed by Oliver Hunt.
This adds inlining of ResolveGlobal accesses that are known monomorphic. It also
adds the specific function optimization to ResolveGlobal, when it is inlined. And,
it makes internal functions act like specific functions, since that will be the
most common use-case of this optimization.
This is only a slighy speed-up (sub 1%), since we don't yet do the obvious thing
with this optimization, which is to completely inline common "globally resolved"
function and constructor calls, like "new Array()".
