llvm-6502/test/Transforms/GlobalOpt/ctor-list-opt-constexpr.ll
Chris Lattner 1945d58025 reapply r121100 with a tweak to constant fold ConstExprs with TargetData
(if available) as we go so that we get simple constantexprs not insane ones.
This fixes the failure of clang/test/CodeGenCXX/virtual-base-ctor.cpp
that the previous iteration of this patch had.
