This CL adds regression tests for two bugs where the wrong native
context is used when lazy accessors are instantiated.
The first bug injects an object created in context 1, into another
context 2. The object has an accessor pair installed via
FunctionTemplate. In context 2, the property descriptor of this
accessor is retrieved, causing the JSFunction to be instantiated
with the current context (context 2) instead of the creation
context of the object (context 1).
The second bug is similar. When breakpoints are set, the whole heap
is walked and all lazy accessor pairs are instantiated. This again
uses the current context instead of using the context from which
a AccessorPair originates.
