I'm glad you ask! I'm still investigating the errors that led to this addition
(and the one in `llvm/tools/llvm-xray/xray-converter.cpp`) but I suspect this
is due to the recursive nature of these classes.
Both `Module` and `StackIdData` contains self-referencing `SmallVector`. It is
unclear to me why the compiler is trying to instantiate the newly added
`SmallVector` constructor //during// type declaration.
I'll post the compiler errors below the additions.
