9a5fa307 - [ADT] Add `llvm::reverse_conditionally()` iterator (#171040)

[ADT] Add `llvm::reverse_conditionally()` iterator (#171040) This patch adds a simple iterator range that allows conditionally iterating a collection in reverse. It works with any collection supported by `llvm::reverse(Collection)`. ``` void foo(bool Reverse, std::vector<int>& C) { for (int I : reverse_conditionally(C, Reverse)) { // ... } } ```
