Implement projectExistentialAndUnwrapClass
Implement a version of projectExistential tailored for LLDB. There are 2
differences when projecting existentials for LLDB:
1 - When it comes to existentials, LLDB stores the address of the error
pointer, which must be dereferenced.
2 - When the existential wraps a class type, LLDB expects the address
returned is the class instance itself and not the address of the
reference.
This patch also adapts the swift reflection test machinery to test
projectExistentialAndUnwrapClass as well. This is done by exposing
the new functionality from swift reflection test. It is tested in
existentials.swift, and ensures that the typeref information is
exactly the same as what is expected from projectExistential,
except the out address.
