Mads, may you have a look?

Couple of comments:

1) I'll do obvious ports to other archs after first review path;

2) I don't quite understand what MEGAMORPHIC kind means when describing stub
generators in builtins.h as for element loading we don't go megamorphic AFAIK,
if you can educate me here, that'd be cool.  My current hypothesis is 'we might
need it later'

LGTM

We use MEGAMORPHIC for all the keyed load stubs because they all work for many
forms of objects (nothing map specific).  We have no MONOMORPHIC keyed load
stubs.
