Functions
static bool	canUnwind (const Function &F)
	Not being nounwind is the default in IR, so that alone is not enough: uwtable is how a frontend asks for unwinding through a function to work.

Variables
static constexpr StringLiteral	UnwindRaise = "_Unwind_RaiseException"
	On other targets it is a function of the unwinder library, which is why nothing else in LLVM knows the name.
