[PATCH] D43330: [gtest] Add PrintTo overload for StringRef.

[Sam McCall via Phabricator via llvm-commits]

sammccall added a comment.

FWIW I'm fine with putting it in `StringRef.h` or here, (`custom/gtest-printers.h`is strictly better than here though).

While I like `llvm/Testing` in principle, the fact that the test compiles and runs fine if you forget to include it, and just gives terrible error messages when it starts failing, seems like a recipe for disaster.
