Summary:
If a struct type S has a member T that has a member that is a function that
returns a typedef of S* the respective field would be duplicated, which caused
an assert down the line in RecordLayoutBuilder. This patch adds a check that
removes the possibility of trying to resolve the same type twice within the
same callstack.
This commit also adds unit tests for these failures.
Fixes https://llvm.org/bugs/show_bug.cgi?id=20486.
Patch by Cristian Hancila.
Test Plan: Run unit tests.
