Is this right/ok?

NOT LGTM.

This is working as intended. We are currently moving toward having
MayNamedAccess only called from handlified code (i.e. code where references to
heap objects are kept via handles). The reason for that is that we want to allow
the embedder to be able to do more complex things in the access callback,
including allocation on the V8 heap. That however could trigger GC. If the
objects referenced in the stack frames below are not via handles, and those
objects are moved by the GC, then those references become invalid. The work on
this is not done yet, so the access callback is still restricted, but this CL
would revert part of the progress.

I just thought it would be ok, because MayNamedAccessWrapper is said to be
temporary and is just an wrapper around MayNamedAccess().

In any case I have closed this CL.

Thanks for taking time to review it though!
