This works in the ICs since compiled handlers are not shared anymore.
As drive-by cleanup I also removed custom code to deal with compiled handler sharing for primitive and access-checked objects.

In case of LAP(lazy accessor pair), the function's creation context
must be equal to the accessor holder's creation context, so this CL
changes the current context to the accessor holder's creation context.
Note that this is the second attempt after https://crrev.com/2770003002
The change from the previous attempt is to skip looking for the
object's constructor if the object itself is a function.
Also some of Blink's LAP-context-sensitive tests got updated at
https://crrev.com/c/597990 and the rest of the tests will get
temporarily disabled at https://crrev.com/c/605408 .
