Reland r22460 - "Bootstrapper::DetachGlobal also need to unset g..."

| DetachGlobal detaches original context of a global proxy object.
|
| Before this patch, the constructor JSFunction still carried a
| reference to the old context after |Bootstrapper::DetachGlobal|
| call.
| This patch removes the reference by setting the constructor
| null.

Tests that the GC doesn't mistake non-pointer constant pool entries as pointers.

Adds a test for ConstantPoolArray to ensure that the GC
doesn't mistake non-pointer entries as pointers and try
to modify them during scavenge operations.

Also adds asserts to ConstantPoolArray::set(int, *Object) to
ensure we don't add new-space pointers in constant pool
array.
