Add an override to StringRef::getAsInteger which parses into an APInt.
...
It gets its own implementation totally divorced from the (presumably
performance-sensitive) routines which parse into a uint64_t.
Add APInt::operator|=(uint64_t), which is situationally much better than
using a full APInt.

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.

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.
