Don't you want to add all paths (also for dict-elements) for normalization?
Makes things easier to understand, at least for me.

See one comment, you still have a bug I think.

https://codereview.chromium.org/1802733002/diff/20001/src/elements.cc
File src/elements.cc (right):

https://codereview.chromium.org/1802733002/diff/20001/src/elements.cc#newcode...
src/elements.cc:2415: }
I think you have to push this up to SloppyArgumentsAccessor or add a check again
in objects.cc:5723 since you no longer separately extract the backing store from
the sloppy arguments, you might end up normalizing a SlowSloppyArguments.
