Douglas Gregor 09470e6a4e Switch StringRef::edit_distance over to using raw pointers, since both 
std::vector and llvm::SmallVector have annoying performance
tradeoffs. No, I don't expect this to matter, and now it won't.

Douglas Gregor 5639af4eac Document the edit-distance algorithm used in StringRef, switch it over

Daniel Dunbar c827d9ee0e Workaround what I believe is an MSVC bug where it emits a definition for a 
static const class member into each translation unit, with external linkage???
 - If someone understands this issue better, please clue me in, I haven't
   consulted the standard yet.
