D137531 <https://reviews.llvm.org/D137531> had once fixed the issue. However, it caused a crash during compiling 
llvm/unittests/IR/PatternMatch.cpp in stage-2. The reason is the predicator 
`isDerivedFrom` does not consider independent types if the derived type is 
dependent.

This patch improves D137531 <https://reviews.llvm.org/D137531> by adding an option to make `isDerivedFrom` consider 
independent types.
