bd65f192f2 enhance raw_svector_ostream::write_impl to work with unbuffered streams, 
which may call write_impl on things that are not the usual buffer.

cdbc36f961 Reimplement getToken and SplitString as "StringRef helper functions" 
- getToken is modeled after StringRef::split but it can split on multiple
  separator chars and skips leading seperators.
- SplitString is a StringRef::split variant for more than 2 elements with the
  same behaviour as getToken.

b7161a0b1c 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.

c6cdebbedd Substantially optimize APFloat::toString() by doing a single large divide to 
cut the significand down to the desired precision *before* entering the
core divmod loop.  Makes the overall algorithm logarithmic in the exponent.

There's still a lot of room for improvement here, but this gets the
performance back down to acceptable-for-diagnostics levels, even for
long doubles.
negligible, even on long doubles.

c71c44ec7f Add accessors for the largest-magnitude, smallest-magnitude, and

Provide an APFloat-to-string conversion which I am quite ready to admit could
be much more efficient.

3f7cf289ed Provide dbgs(), a circular-buffering debug output stream. By default it 
simply passes output to errs().  If -debug-buffer-size=N is set N > 0,
dbgs() buffers its output until program termination and dumps the last N
characters sent to it.  This is handy when debugging very large inputs.
