[PATCH] D43239: Improve internal StringSwitch code gen with Optional<T>

[David Zarzycki via Phabricator via llvm-commits]

StringSwitch currently fakes Optional<T> by storing a pointer to the result. The problem with this approach is that it forces the compiler to store all case results on the stack before entering the string switch just so the address of the result can be temporarily used.
