This resubmits a3770391c5fb64108d565e12f61dd77ce71b5b4f, which was reverted due to breakages on non-Windows machines. Due to differences in template instantiation rules on Microsoft and non-Microsoft platforms, a member access restriction was triggering on non-Microsoft compilers. Previously, a friend declaration for std::vector<> had been introduced into the DebugMap class to make the member access restriction pass, but the introduction of support for SmallVector<> meant that an additional friend declaration would need to be added. This didn't really make a lot of sense since the user of the macro is probably only using one type (SmallVector<>, vector<>, etc) and we could in theory add support for even more types to this macro in the future (e.g. std::deque), so rather than add another friend declaration, I just made the type being referenced a public nested typedef instead of a private nested typedef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@277888 91177308-0d34-0410-b5e6-96231b3b80d8
