Port r9030 and part of r9016 to 3.3 branch.

Port r9030 and part of r9016 to 3.3 branch.

Made FromPropertyDescriptor not hit inherited setters.

Changed computation of func.caller to skip some built-in functions. 
Now skips built-in functions called from other built-in functions,
so only the initally called built-in function is exposed.
